In practical applications, some occasions require the conversion of AC power into DC power, which is the rectifier circuit. In other occasions, the DC power supply needs to be converted into AC power. This reverse engineering corresponding to rectification is defined as an inverter circuit. Under certain conditions, a set of thyristor circuits can be used as both a rectifier circuit and an inverter circuit. This device is called a converter, including rectifiers, inverters, AC converters and DC converters.
