Advancing Endoscopy Technology with AC/DC Power Supplies and DC/DC Converters

Bus Temperature Controller in Photovoltaic Laminating Machine

The “14th Five-Year Plan” in China emphasizes the advancement of energy revolution, aiming to build a clean, low-carbon, safe, and efficient energy system, while enhancing the energy supply security capacity. The plan accelerates the development of non-fossil energy sources, advocating both centralized and decentralized energy generation, and promotes the growth of clean energy bases, including wind power and photovoltaic (PV) power generation.

Photovoltaics have become the main force in the new energy system. Photovoltaic technology utilizes the photovoltaic effect at semiconductor interfaces to directly convert light energy into electrical energy. It primarily consists of three components: solar panels (modules), controllers, and inverters.

Process Flow of Solar Panel (Module) Manufacturing:

Laminating is a critical step in the production of solar panels. The pre-laid solar cells are placed in the laminating machine, where the air inside the components is evacuated through vacuum suction. The Siemens CPU host, using the Profinet-RT bus protocol, connects the AU7 697H-0RH22-PNT+SM633H-1RF22-P combination to read the thermistor values. The PID parameters then control the even heating of the laminating machine’s heating plate, causing the EVA (Ethylene-Vinyl Acetate) to melt and bond the solar cells, glass, and backsheet together. Finally, the AU7 697H-0RH22-PNT+SM633H-1RF22-P combination cools the components and removes the finished module.

The AU7 temperature control coupler is highly expandable, supporting up to seven modules. The coupler features 16 built-in PID control loops and can handle up to 40 temperature control channels. It includes 16 digital output channels and 16 thermistor/thermocouple input channels, integrating 40 intelligent fuzzy PID temperature control algorithms, powered by 24VDC.

Leading the Trend of Bus-based Intelligent Temperature Controllers

The AU7 series represents a breakthrough in traditional temperature control systems, offering programmable and highly intelligent capabilities. The high-speed bus and rapid temperature control capabilities position it at the forefront of a new era in industrial temperature management.

With its classic technology, the AU7 is reliable and stable, setting a new standard for modern temperature control solutions.

Here’s the translated and structured English article: Powering UAVs: DC-DC Converters for Diverse System Power Solutions

Some might argue that the first unmanned aerial vehicle (UAV) was the hot air balloon introduced by Montgolfier in 1783. However, the flight path of a free-floating hot air balloon was dictated entirely by the wind.

In 1892, Thomas Edison demonstrated a wire-guided torpedo, and in 1898, Nikola Tesla introduced his radio-controlled boat. Decades later, the first remote-controlled unmanned cars and planes entered the market. Today, UAVs are utilized for applications ranging from toys to autonomous, guided, or remote-controlled flying, driving, or diving vehicles.

Basic UAV Power Architecture – Examples of Power Solutions for UAV Systems

All these devices face several common challenges, the most important being safe operation to prevent collisions with people or objects and uncontrolled crashes. UAVs need to be lightweight yet powerful enough to carry significant payloads and operate for extended periods.

While applications often involve small quantities, specific configurations of sensors, manipulators, or monitoring devices may be required for different scenarios. Manufacturers can address this need using flexible modular platforms and off-the-shelf components to quickly and cost-effectively tailor solutions.

How are these vehicles powered?
The answer depends on the application and required operational time. For short-term operations, batteries or supercapacitors are sufficient. Modern fuel cells extend operation time, while internal combustion engines or tethered power supply systems are viable for long-term use.

Providing reliable power to onboard electronics is critical for ensuring safety, extended operation, and payload efficiency. With varying source voltages and the need for stable power supply voltages across loads, power delivery becomes a crucial challenge. P-DUKE’s power modules offer flexible and modular solutions to address these needs.

Onboard power architectures for UAVs—whether airborne, ground-based, or underwater—are similar. These systems typically comprise power supplies, DC-DC converters for various loads, speed controllers, and propulsion motors.


Key UAV Power Solutions and Examples

UAV Power Supply Architecture

In most applications, propulsion motors are directly powered by the power source to avoid additional conversion losses. UAV systems often use battery packs where voltage and capacity depend on system size and maximum power. Motors are typically powered directly by the batteries, while the remaining components require stable voltages.

For drones, lithium-polymer batteries connected in series deliver nominal voltages ranging from 11.1V (3S) to 59.2V (16S). For longer flight times, fuel cells may be used.

Modern warehouse robots—both autonomous (UAV) and guided (UGV)—use lithium-ion or LiFePO4 batteries with nominal voltages from 24V for smaller systems to over 100V for heavy-duty applications like forklifts.

Selecting the Right DC-DC Converters for UAV Power Systems

Designers seeking flexible, modular power solutions for various applications face a challenge with wide voltage ranges. P-DUKE offers a comprehensive range of DC-DC converters with input voltage ranges of 9–75V and 14–160V, single or dual output voltage options from 3.3V to 48V, and power levels from 10W to 200W.

High-efficiency, compact DC-DC converters also reduce overall weight and facilitate thermal management by distributing heat generation across the system, close to the load.


Case Studies in UAV Power Applications

Autonomous Factory Vehicles (Warehouse Robots)

These vehicles, operating in smart factories, use lasers and cameras for navigation and communicate directly with manufacturing systems. Their power architecture often features 24V or 48V batteries for motors and onboard electronics.

Key components include:

  • P-DUKE’s HAE150W series for 12V power.
  • UDH03 and PDL12W series for 5V loads.
  • OSR03 series for 3.3V sensors and CPUs.

Supercapacitor-Based Robots

For low-power applications requiring short bursts of operation and fast charging, supercapacitors offer a viable alternative. These devices deliver high peak currents and boast over a million charge cycles with minimal performance degradation, making them cost-effective in the long run.

A typical power architecture for supercapacitor-powered robots includes:

  • P-DUKE’s QAE100U series, which handles voltage swings from 12V to 48V.

Helicopter UAVs with Fuel Engines

Small unmanned helicopters with flight times exceeding four hours often rely on fuel engines. Typical architectures include a rotor-driven propulsion system and a 28V power bus for onboard electronics like LiDAR, 3D mapping systems, and geotagging tools.

For such applications, lightweight DC-DC converters like the P-DUKE HAE200W series are ideal. With an operational temperature range down to -40°C and MIL-standard shock and vibration resistance, these converters deliver up to 212W of power with minimal weight impact.

Remote Control Systems

Remote control units often require robust 28V RF amplifiers. Powering these systems involves:

  • P-DUKE QAE100U series for main 28V bus.
  • Low-power converters for downstream voltage requirements (12V, 5V, 3.3V).

Conclusion

Every UAV application presents unique challenges and requirements. However, common demands include compact size, lightweight design, high efficiency, reliability, modularity, and ease of use. Manufacturers like P-DUKE offer comprehensive power solutions to meet these challenges, enabling designers to create flexible and effective UAV systems.

Schneider Electric: Empowering Process Industry Transformation with Open Automation and Digitization

Against the backdrop of accelerating digital transformation in the global industrial sector, the process industry, as an important foundation of the national economy, is facing unprecedented opportunities and challenges. How to maintain competitiveness and achieve efficient and sustainable development in this transformation has become a focus of attention for many enterprises.
On October 23, 2024, Industrial Control Network and multiple media outlets gathered in Shanghai to participate in the highly anticipated 2024 NAMUR China Annual Conference.

The theme of this year’s conference is “Open Automation and Digitalization, Empowering Enterprises for Efficient and Sustainable Development”. It brings together technical experts from NAMUR member units such as BASF, Bayer, Covestro, and Chongqing University of Posts and Telecommunications to explore how to empower the process industry with open automation and digital technology, and achieve an efficient and sustainable future.

Over the past 75 years, NAMUR has not only witnessed the evolution of automation technology, but has also played an important role in promoting technological innovation, standard setting, and talent development.
