Abstract

A simplified shoot-through pulse width modulation (PWM) technique is presented for reducing switching losses in impedance source DC-DC converters. The proposed PWM method alternates shoot-through state conduction in each leg of the H-bridge, thereby increasing controllability of the converter, reducing the number of switching transients, and reducing the dynamic loss of the converter through soft-switching. The proposed modulation method was verified using a GaN-based quasi-Z-source DC-DC converter. This method demonstrates better performance at low load and with high switching frequency.
