基于SG3525控制与IR2110驱动的Buck电路Saber仿真

The Saber Simulation of Buck Circuit Based on SG3525 Control and IR2110 Drive

本文介绍了一种Buck电路,控制芯片选用了SG3525,驱动电路选用IR2110,功率开关器件选用apt35g60,利用Saber软件进行仿真。控制芯片SG3525产生PWM波通过IR2110来驱动IGBT apt35g60,最后仿真波形说明了系统电路的可行性,可以看出电路输出波形稳定。

This paper introduces a Buck circuit.The control chip uses SG3525,the driving circuit uses IR2110,and the power switching device uses apt35g60.Saber software is used to simulate the whole circuit.The control chip SG3525 generates PWM waves and drives IGB T apt35g60 through IR2110.Finally,the simula tion waveform illustrates the f easibility,and it c an be seen tha t the output volt age of the cir cuit is s table.
