Energy efficient power supply system of induction heating plant

The power supply system presented in the article is used to power the induction converter of the induction heating plant for metal products with a discrete cross-sectional area (for example, metal balls). The system is based on an active current rectifier (CSR). This active rectifier allows maintaining the shape of the network current close to sinusoidal, as well as regulating the current at the input of the inverter of the induction converter at a given level.
