Abstract:
A sinusoidal modulation method and a three-phase inverter are disclosed. A pulse driving signal controller is disposed to connect the three-phase inverter. The pulse driving signal controller controls the transistors of the three-arm full-bridge architecture. By examining the phase angle of the output current, operations of the upper and lower bridge power transistors can be adjusted, so that three power transistors are turned on and the other three power transistors are turned off during the PWM operations. As a result, the dead time is not required to set during the PWM operation for preventing a short-circuit due to dynamic switching errors of the upper and lower bridge power transistors. The requirements of the hardware circuits can be also reduced.

Claim (Index 2):
The sinusoidal modulation method according to  claim 1 , wherein the output terminal of the three-phase inverter is serially connected to an inductive circuit comprising an inductor and a resistor, and a phase-shift angle of current lagging voltage is obtained by detecting an inductive reactance of the inductor and a resistance value of the resistor.
