摘　　要：在中小功率逆变应用中,半桥电路使用的功率器件少,结构简单,因此得到广泛应用.针对半桥逆变电路建立等效模型,用交流电源等效代替开关器件,根据叠加原理得到电路传递函数,并给出设计PID调节器的方法,通过实验验证其有效性,实现50～750 Hz正弦电流输出.Due to less power devices and simple structure,halfbridge circuit is widely used in the field of middle and low power inverters.An equivalent transformation of the half-bridge inverter topology was presented,which the power devices were replaced by an AC voltage source,and the transfer function was obtained based on the superposition theorem.A(design) method of PID compensator was given and was validated by experiments.The output frequency ranged from 50~750 Hz was realized.
