| Abstract: | The effect of the control feedback by the instantaneous value of an output voltage on thewaveform of PWM inverter modulating signals is discussed.To achieve better voltage uti-lization,a scheme with the injection of the third-order harmonic into the PWM inverter cir-cuit is proposed.Computer simulation and experimental results show that the scheme pro-posed is feasible and satisfactory.It has been used in an inverter with IGBT with a capacityof 40 kVA. |
