Transient angle stability of the inverter is influenced by the RPC loop. With the increase of the output voltage of the RPC loop, reference reactive power, and output voltage of the inverter, transient angle stability of the inverter can be improved.
An ideal voltage source inverter keeps the voltage constant through-out the process. A VSI usually consists of a DC voltage source, voltage source, a transistor for switching purposes, and one large DC link capacitor. A DC voltage source can be a battery or a dynamo, or a solar cell, a transistor used maybe an IGBT, BJT, MOSFET, GTO.
A typical voltage source inverter consists of power semiconductor devices (such as insulated gate bipolar transistors or IGBTs), gate driver circuits, control circuits, and filtering elements. What is the difference between a voltage source inverter and a current source inverter?
Lower fundamental output voltage: The output voltage waveform of a 120° conduction mode inverter has a lower fundamental voltage compared to the 180° conduction mode, which may impact certain applications. Motor Drives: Inverter-fed induction motors and synchronous motors can be controlled using a 120° conduction mode inverter.
