This paper presents a new shoot-through control method applicable for an impedance source galvanically isolated DC/DC converter. In impedance source converters, the introduction of shoot-through states increases the switching speed of H-bridge switches about two to three times the switching frequency. This approach reduces the switching transient of all switches of inverters by commutating them once in a switching cycle. The shoot-through states are generated by alternatively switching the single leg of the inverter whereas, in baseline modulation approach, all the switches are turned on during shoot-through states. This method decreases the switching loss of front-end converters and independent controllability of active and shoot through states. This modulation technique is applied and validated to a voltage-feed Quasi-Z source isolated DC-DC converter with a voltage doubling rectifier.
