ABSTRACT:
A two-phase driver comprises two H-bridge circuits each of them including a transformer and two switch assemblies connected to the opposite terminals of the primary side of the transformer, in which one of the switch assemblies is shared by the two H-bridge circuits. Each of the switch assemblies includes a high-side switch and a low-side switch, and each of the high-side switch and low-side switch is switched by a respective signal so as to modulate the loading currents supplied to two loading loops connected to the two H-bridge circuits, respectively.
