A sine wave synthesis controller circuit intended to be utilized in conjunction with a digitally-controlled neutral-point clamped inverter to produce a sinusoidal waveform from a direct current source. The controller circuit is configured so that it provides separate positive and negative control signals to the neutral-point clamped inverter's logic controller. These signals direct the modulation a sinusoidal waveform in response to a reference sine wave, the instantaneous voltage output by the neutral-point clamped inverter, as well as positive and negative reference voltages input to the controller.
