Abstract
Adding a resonance link to the traditional PWM inflexible switching circuit, a voltage-source inverter of high frequency and no switching less was formed. Compared with current PWM inverters, this circuit has the advantages of high frequency, low noise, low switching-loss, little system volume, low electromagnetic interference, quite good output wareforms and no need of damping circuit.
