摘要： Proposed is a driver having dead-time compensation function. The driver having dead-time compensation function generates an output voltage according to a voltage command and a frequency command. The driver includes an inverter, an output current detector and a control unit. The inverter receives a DC voltage and operates with a pulse width modulation mode so that the driver outputs the output voltage and an output current. The output current detector detects the current value of the output current to generate a output current detecting signal. The control unit outputs a switching control signal to inverter according to the voltage command and the frequency command. The control unit corrects a reference command according to dead-time and the output current detecting signal related to the output current so that amplitude and waveform smoothness of the output voltage and the output current are compensated.
