초록

Inverter is classified into voltage source and current source by the circuit's configuration. VSI (voltage source inverter) has the excellent generality, economical effects and high power-factors. CSI (current source inverter) is proper to frequent acceleration and deceleration of induction motor, the energy recovering accomplished to ac power line without any other device. But CSI inverter have some troubles such that the numbers of components are increased and the circuits are complicated. To solve these problems, a new inverter is proposed in this paper. This method gives protection of inverters when appears both an instantaneous load-open circuits and an instantaneous load-short circuits, and it has the both merits of both VSI and CSI.
