摘　　要：为解决移相全桥电路驱动及相角控制问题,设计了一种数字控制的移相全桥驱动电路.以TPL521为光耦隔离、IR2110为栅极驱动芯片.由DSP产生PWM信号,经过光耦隔离和逻辑电路后送至IR2110进行相角控制.文章对IR2110驱动电路原理进行分析及参数进行设计,对TMS320F28335进行设置并给出部分代码.实验结果表明:通过TMS320F28335可产生的不同相角的PWM波形,满足了移相全桥对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.
