ABSTRACTThe flyback power stage is a popular choice for single and multiple output dc-to-dc converters at powerlevels of 150 Watts or less. Without the output inductor required in buck derived topologies, such as theforward or push-pull converter, the component count and cost are reduced. This application note will reviewthe design procedure for the power stage and control electronics of a flyback converter. In these isolatedconverters, the error signal from the secondary still needs to cross the isolation boundary to achieveregulation. By using the UC3965 Precision Reference with Low Offset Error Amplifier on the secondaryside to drive an optocoupler and the UCC3809 Economy Primary Side Controller on the primary side, asimple and low cost 50 Watt isolated power supply is realized.

為解決移相全橋電路驅動及相角控制問題,設計了一種數字控制的移相全橋驅動電路.以TPL521為光耦隔離、IR2110為柵極驅動芯片.由DSP產生PWM信號,經過光耦隔離和邏輯電路后送至IR2110進行相角控制.文章對IR2110驅動電路原理進行分析及參數進行設計,對TMS320F28335進行設置并給出部分代碼.實驗結果表明：通過TMS320F28335可產生的不同相角的PWM波形,滿足了移相全橋對不同相角控制的要求.In order to solve the problem of phase-shifted full-bridge circuit driving and phase angle control,a digitally controlled phaseshifted full-bridge driving circuit was designed. TPL521 optocoupler isolation,IR2110 gate driver chip. PWM signals are generated by the DSP and sent to the IR2110 for phase angle control after optocoupler isolation and logic circuits. This text carries on the analysis to the principle of IR2110 drive circuit and parameter design,set up and give out some code to TMS320F28335. The experimental results show that the PWM waveforms with different phase angles generated by TMS320F28335 can meet the requirements of phase-shifted full-bridge control for different phase angles.
