scripts default iconThree-Phase AC-DC-AC PWM Converter (Scripts) Publisher's description

A 50 kW, 380 V, 50 Hz load is connected to a 25 kV

A 50 kW, 380 V, 50 Hz load is connected to a 25 kV, 60 Hz grid through a AC-DC-AC power supply. This power supply consists of two voltage source converters, VSC1 and VSC2, connected through a DC link.

VSC1 connected on 60Hz grid is operating as a rectifier. It regulates the DC link voltage at 750V and keeps unity power factor on AC grid. The PWM chopping frequency is 1980 Hz.

VSC2 connected on 50 Hz load is operating as an inverter. It generates a 50 Hz frequency and regulates load voltage at 380 Vrms. The PWM chopping frequency is 2000 Hz.

The electrical circuit is discretized at 2 microseconds. The sampling time of the VSC1 and VSC2 control systems is 100 microseconds.
