摘要：

In order to make the robot lighter, minimize the size, and have good heat dissipation, the technique of high power density DC-DC converter design is necessary. It can minimize the internal circuit in the robots, improve heat dissipation, and have high efficiency. Therefore, adoption of a forward converter synchronous rectification is used. This technique can diminish the loss of diode forward so it is able to increase the conversion efficiency. The active clamp reset transformer is used on primary-side to make Transformer demagnetization. At the same time, the power MOSFET can achieve the goal of zero voltage switching function, improving the efficiency of the converter. Finally, the forward converter is made with operating frequency of 300k Hz and 100W output power, and the maximum efficiency is 92.4%.
