New control method of bidirectional isolated dc/dc converter — Control system which can obtain output voltage much higher than winding ratio of transformer

A new control system of the bidirectional isolated dc/dc converter will be presented. The output terminals of two single phase bridge inverter A and B are connected through an isolated transformer, and the pulse width of the inverter of higher d.c. voltage is narrowed to make equal the fundamental a.c. voltage of both inverters.
