Full-controlled devices and SCR consisting of the mixed H bridge switch circuit

Usually the H bridge switch circuits of four power switches are all the full-controlled devices, where two of them are the low-end switched and two as the high-end switches. The low-end switch driver is simpler, and the high-end switch driver is relatively complicated. In this paper, a kind of use full-controlled devices and SCR consists of a mix of H bridge switch circuit was presented, in which, the low-end switches use full-controlled devices, high-end switches use SCR. Using SCR conductive self-locking characteristics, this H bridge switch circuit can make the high-end switch driver also became very simple, so simplify the H bridge driving circuit.
