Abstract:
Disclosed is a power control driving device which includes a sine wave signal generating unit; a control signal converting unit configured to convert a sine wave from the sine wave signal generating unit into a multi-bit control signal; and a three-phase inverter circuit configured to output a voltage varied by the multi-bit control signal from the control signal converting unit. The control signal converting unit includes a multi-bit sigma-delta modulator configured to convert an analog sine wave into a digital signal. The three-phase inverter circuit includes a plurality of switch units, on-off states of the plurality of switch units being controlled according to the multi-bit control signal from the control signal converting unit.
