Abstract
A switching circuit is provided to process a DC voltage and apply a low frequency AC voltage, having a trapezoidal waveform, to a co-axial cable transmitting the low frequency AC voltage to a load which may be powered by the low frequency AC voltage as well as a DC voltage. In one specific embodiment two of the switches are connected as part of buck regulation circuits to serve a dual purpose of polarity switching and regulation.
