Abstract
The present invention discloses an inverter circuit and a method for supplying an inverted voltage. The method for supplying an inverted voltage comprises: providing a power switch and an inductor electrically connected with each other; driving the gate of the power switch by a driver gate, such that an input voltage is converted to a negative voltage supplied to a load; and providing a low operation voltage to the driver gate according to the negative voltage.
