Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A digital phase converter creates a three phase power supply from a single phase supply. A digital signal processor is used to control power electronic devices to generate a third voltage, which along with the single-voltage from the supply creates a balanced three-phase power supply. AC power from the utility is converted to DC, then back to AC. The power switching devices used in this process are insulated gate bipolar transistors. In one type of digital phase converter the input rectifier consists of IGBTs in series with inductors. The IGBTs are controlled by software in the DSP to draw current from the single-phase line in a sinusoidal fashion, charging capacitors on a constant voltage DC bus. Because the incoming current is sinusoidal, there are no significant harmonics generated back onto the line as there are with the rectifiers found in most VFDs. Thecontrolled rectifier input allows power factor correction.show more
