This paper presents single stage series load resonant ZVS-PWM high frequency inverter which operates one diode conduction mode and critical ZCS PFC rectifier for induction heating (IH) applications. This single stage inverter is composed of a single phase PFC rectifier operating at one diode conduction mode and asymmetrical ZVS-PWM high frequency resonant inverter without the interlink bulky electrolytic...
Most modern variable-speed motor drives are based on pulse width modulated voltage source inverters, supplied from a smooth DC link voltage. This is often obtained from a three-phase diode bridge mains rectifier with a large output capacitor to keep the DC link voltage essentially constant. The AC currents at the input of the bridge are often discontinuous and contain high levels of harmonics. Harmonic...
This paper proposes novel high input power factor single-stage single-phase AC/AC converter to give high input power factor and low current distortion on the rectifier side and provide clean and stable AC voltage on the inverter side. The proposed AC/AC converter can not only provide regulation of the output AC voltage magnitude but provide variable output AC voltage frequency. A significant reduction...
