Abstract
This paper proposes a method of constant voltage hysteresis width of hysteresis loop control method for the single-phase half bridge inverter , which also achieves zero current switching ( ZCS) by output feedback current .The traditional inverter works under the mode of continuous conduction mode ( CCM) , which causes the great loss of swit-ches, and the low working efficiency .The method of adding resonant circuit on the hardware to realize the soft switch can reduce the loss of switch tube , while the overall efficiency of the inverter cannot be enhanced .Therefore , this pa-per proposes a method of constant hysteresis band voltage-controlling inverter , which makes the inverter work under the mode of discontinuous conduction mode ( DCM) , it can not only greatly reduce the volume of filter inductor , and also can reduce the opening loss of switch tube , thus improving the working efficiency of inverter .Furthermore, this paper analyzes the relationship between the hysteresis width and the total harmonic distortion rate of output voltage .A linear relationship is analyzed based on simulation results , and the quantitative function relationship is obtained .关键词
