Active three-phase rectifiers operated at switching frequencies of 500 kHz and above, in order to increase their power density, require high-speed current controllers. If these current controllers are implemented purely digitally, which is well estab

The output center-point voltage of a hysteresis current-controlled three-level, unidirectional PWM rectifier is not naturally stable. This paper shows that the balancing of the center-point voltage can be realized by adding an offset to the input cur
