Abstract
The invention provides a switching system. The switching system comprises an H bridge, a current router, and a control circuit. The H bridge comprises a first switch and a second switch coupled to a first output node and a third switch and a fourth switch coupled to a second output node, wherein a load is coupled between the first output node and the second output node. The current router comprises a first shunt switch and a second shunt switch coupled between the first output node and the second output node. The control circuit generates a first control signal to control the first switch and the fourth switch, generates a second control signal to control the second switch and the third switch, generates a third control signal to control the first shunt switch, and generates a fourth control signal to control the second shunt switch.
