Abstract: An inverter apparatus having a power supply circuit includes a converter circuit for rectifying AC power into DC power, a smoothening circuit for smoothening the rectified DC power, an inverter circuit for converting the smoothened DC into AC at a variable frequency through a plurality of switches to control a load, and a current detection circuit for detecting overcurrent from the smoothened DC supplied from the inverter circuit, wherein the inverter circuit applies bootstrap power for driving the switches to the current detection circuit to use the bootstrap power as power of the current detection circuit. When bootstrap power for driving switch gates is used, it is possible to use the bootstrap power as the power of the current detection circuit by adding the auxiliary circuit composed of a small number of passive elements.

Abstract: The present disclosure provides a motor drive device and a motor drive system for improving a control stability despite an imbalance in zero crossing points in a sensorless motor of which position of a rotor is estimated by a counter electromotive force. The motor drive device includes: a position detector configured to detect a rotational position of a rotor of a motor by detecting a plurality of zero crossing points of a counter electromotive force induced in the motor; and a controller configured to control the motor by estimating a phase change timing based on a time interval between a current zero crossing point and a previous zero crossing point of a same state as the current zero crossing point among the plurality of zero crossing points detected by the position detector.
