A power supply including an inverter receiving a DC input signal from a DC input source ( 11 ). The inverter is implemented as a single-ended inverter. Each inverter is driven by a signal source ( 13 A, 13 B), which outputs an AC signal. The output from each inverter is input to a first stage harmonic filter. The power supply includes an output circuit that includes a rectifier (D 1 ) arranged about a point so that if the inverter attempts to drive the point beyond a predetermined voltage, the rectifier conducts in order to return at least one of power and current to the DC input source. The output from the first harmonic filter (L 1 A, C 1 ; L 1 B, C 1 ) is output to a second harmonic filter (L 2 , C 2 ) and is then output from the power supply. |
