ABSTRACT:
An inverter apparatus includes a flip-flop circuit and a voltage clamp circuit disposed in the upper arm, and set and reset signal generators each having a series connection of two switching devices. By using an input signal and using an output signal of the flip-flop circuit, the above described two switching devices are activated in a complementary manner. Owing to this configuration, no current flows except a minute time for supplying a trigger signal to the flip-flop circuit, resulting in low current consumption. If the output logic of the flip-flop circuit has been inverted by noise, two switching devices are simultaneously in the on-state and a re-trigger current is let flow to restore the above described output logic to the normal state, resulting in the complementary state again. As a result, signal transmission between the upper and lower arms is performed at higher speed and with a lower loss. In addition, the inverter apparatus is protected from false operation due to noise.
