Abstract :
A multi-functional system is proposed in this paper, which adopts high power controllable turn-off power transistors as the core of its converter and adopts the technology of sine pulse width modulation (SPWM) to control the opening and closing of them. It can be used for rapid automatic power grid synchronization, ring net parallel operation, voltage boosting, current boosting , and other functions. In this paper, the multifunctional system and its applications are also discussed.
