ABSTRACT:
An inverter circuit to reduce a resistor for overcurrent detection and decrease the number of filters in an inverter circuit for supply polyphase power. Transistors each having a current detection terminal and a protective diode for regenerative current are adopted as switching elements on an “L” side and their current detection terminals are connected in common to a resistor. Therefore, a voltage drop caused by a current flowing in the resisytor becomes larger when an overcurrent flows in at least one of the transistors and further when an overcurrent flows in a switching element on an “H” side even if no overcurrent flows in any one of the transistors.
