Abstract:
A load control device to control current flow to an AC load includes a circuit having line-side switches and floating-neutral side switches, along with a controller connected to the circuit that is programmed to control the circuit so as to cause each of the line-side switches and each of the floating-neutral side switches to switch between an On condition or an Off condition to selectively operate the circuit in an active mode and a free-wheeling mode. A full phase voltage is provided to the AC load during the active mode and a zero voltage is provided to the AC load during the free-wheeling mode. The controller applies a modulating function to the circuit, so as to modulate a supply voltage to control a frequency and an average of a load voltage present across terminals of the AC load, thereby enabling variable frequency operation of the AC load.
