New Type

A new-type LED switching power supply circuit using flyback converter is designed based on current-mode PFC controller chip L6562. The circuit has some characteristics such as simple structure, wide input voltage range, output stability and reliable operation. The experimental results show that the system efficiency is up to 89.46% when the input voltage changes from 85V to 265V(AC), meanwhile the system works stably with constant current and constant voltage output.

Gate Charge

Power supply for Unmanned Aerial Vehicle (UAV) low voltage, high current output, so conventional diode rectifier circuit had been unable to meet the high efficiency in switching power supply, which should selected synchronous rectification (SR). But conventional gate charge retention drive existed dead time and constant drive voltage problems. In this paper, proposes a new gate charge retention drive to improve the phenomenon. Using Saber to analysis the two methods, we could verify the accuracy of the theory. Finally, 72v input 6v/20 output forward converter are designed using the new methods and 90% efficiency is achieved at full load.

Control Accuracy

This paper designs a new type of the control system of switching power supply for audio power amplifier, which is used in DSP-controlled power amplifier. The basic frame and the software and hardware design of the system are described. The system uses TMS320F2812 as the main controller, to reduce the hardware circuit structures, and realize the audio power amplifier digital control. The experimental results show that the design has good regulator function, which not only satisfies certain control accuracy, but also meets the real-time requirements, and has great future in high audio power amplifier.
