本模型是针对DC-DC的搭建，其中采用PWM控制，一般针对充放电时使用(This model is for the construction of DC-DC, which uses PWM control, generally used for charging and discharging.)

此模型为双向DCDC，可用于电池充放电，燃料电池升降压模拟等。采用PWM控制IGBT管占空比。可直接运行，在其基础上修改简单(This model is a bidirectional DCDC, which can be used for battery charging and discharging, fuel cell buck-boost simulation. PWM control of the IGBT tube duty cycle. Can be run directly,
