Abstract: A variable frequency and non-sinusoidal power generator includes a pulse module circuit, a slope module circuit, and first and second cooling systems. The pulse module circuit and the slope module circuit includes control switches, and generates at least one of a output currents and a output voltages by selectively turning on/off the control switches based on control signals. The first and second cooling systems are disposed at first and second sides of the control switches. A bias power having a variable frequency and a non-sinusoidal waveform is generated based on the control signals, at least one of the output currents and the output voltages.
