– Use PCB materials with good thermal conductivity to aid in heat dissipation.

II. Implementing Effective Protection Mechanisms

1.Integrated Protection Features:

– Incorporate overvoltage, overcurrent, short circuit, and temperature protection features to ensure the safe operation of the power supply under any abnormal conditions.

– Design an automatic recovery function to allow the power supply to automatically resume normal operation after the abnormal situation is resolved.

2.Sensitive Detection System:

– Deploy high-precision sensors in the power supply to monitor voltage, current, and temperature in real-time.

– Utilize advanced microprocessors to quickly process abnormal signals and respond accordingly.

III. Optimizing Thermal Management

1.Efficiency Improvement:

– Prioritize improving conversion efficiency during the design phase to reduce heat generation due to power loss.

– Select an appropriate switching frequency to balance efficiency and thermal performance.

2.Cooling System Design:

– Adopt effective cooling designs, such as using heat sinks, fans, or heat pipes.

– Ensure that the layout and size of the cooling components can accommodate the thermal load during prolonged operation.

IV. Conducting Rigorous Testing and Validation

1.Performance Testing:

– Perform comprehensive performance testing on the power supply, including long-term stability testing, load testing, and environmental adaptability testing.

– Utilize advanced testing equipment and software to simulate various operating conditions and load changes.

2.Quality Control:
