简介
An improved shoot-through pulse width modulation (PWM) control technique for quasi-z-source DC/DC converters is presented. The improved modulation technique is derived from PWM control with shifted shoot-through and reduces both switching losses and electromagnetic interference by reducing the number of switching transitions and increasing the proportion of soft switching transitions. The improved modulation technique also simplifies closed-loop control of the converter. A 500W quasi-z-source DC/DC converter prototype was built to verify the effectiveness of the proposed method.
