Abstract：The paper study a novel PWM control strategy in dual buck half bridge inverter topology. The circuit control mode of this PWM control strategy is determined by judging the working state of the inductance. In the continuous current mode (CCM), the inverter adopt voltage outer loop and current inner loop control mothod.And in the discontinuous current mode (DCM), through the analysis of mapping relationship between the discontinuous current duty ratio and continuous one, which makes makes the inverter can be a good control of the output voltage tracking a given value in linear or strong nonlinear operation mode under dual loop control method. The waveform distortion of dual buck inverter under half cycle modulation is greatly reduced.
