Definition: A voltage source inverter or VSI is a device that converts unidirectional voltage waveform into a bidirectional voltage waveform, in other words, it is a converter that converts its voltage from DC form to AC form. An ideal voltage source inverter keeps the voltage constant through-out the process.
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.
The working principle of a voltage source inverter revolves around the utilization of semiconductor switching devices to modulate the DC input voltage into a controlled AC output.
Different energy conversion methods Voltage source inverters use semiconductor switching devices to convert DC to AC, while current source inverters convert DC to AC through power modules, control circuits, filtering circuits and so on.
