With wide‐bandgap transistors, the leakage current through the parasitic transistor to heat sink capacitance is increased with the operation at higher switching transition voltage slopes. This study presents a modulation synchronisation method for a double‐leg boost converter to reduce these leakage currents. Having a similar leakage current path, the transistors turn‐on transition of one leg is synchronised on the turn‐off transition of the second leg.
