Q.10. What do you mean by voltage source converters? [2]
Answer
A voltage source converter (VSC) is a power electronic converter, typically built with self-commutating switching devices such as IGBTs along with anti-parallel diodes, that converts a DC bus voltage into a controllable AC voltage of desired magnitude, phase, and frequency.
- Uses PWM switching to synthesize the AC output waveform from a DC capacitor voltage source
- Forms the core building block of modern FACTS and custom power devices such as STATCOM, DVR, UPQC, and VSC-based HVDC links
