Abstract
A bidirectional inverter circuit for evenly distributing energy among two capacitors in a DC power supply of a pulse width modulated inverter which provides an AC output to a load. The bidirectional inverter circuit is responsive to a greater charge on one of the power supply capacitors than on the other to divert regenerative current flowing to the power supply from the load away from the one capacitor and to transfer charge to the other capacitor.
