Title:
INVERTER DEVICE
Document Type and Number:
Japanese Patent JP3282321
Kind Code:
B2
Abstract:
PURPOSE: To prevent the zero-point fluctuation of a current sensor and, at the same time, to make a smoothing capacitor to quickly discharge electric charges.
CONSTITUTION: An inverter device is equipped with a connector 2 which connects or disconnects a smoothing capacitor 3 to or from a DC power source 1, converter circuit 4 incorporating three sets of switch element pairs Q1-Q6 connected in parallel with each other, three-phase load 6 connected to three feeder lines 41, 42, and 43 extended to the connecting point of each switching element pair Q1-Q6, and magnetic current sensors 5 additionally installed to the feeder lines 41 and 43. The inverter device is also provided with a control section 7 which makes the connector to make disconnecting operations when the operation of the converter device is completed and, at the same time, supplies a single-phase alternating current between the feeder lines 41 and 43 by switching the transistors Q1-Q6 in two phases.
