Title:
INVERTER APPARATUS
Document Type and Number:
Japanese Patent JPH0638545
Kind Code:
A
Abstract:
PURPOSE: To conduct an appropriate selection of brake resistance by displaying the duty cycle of the brake resistance.
CONSTITUTION: When regenerative energy is high, a brake resistance 6 is driven by a brake drive circuit 8, the duty cycle of the brake resistance 6 is measured by a brake resistance duty cycle-measuring circuit 9 and the value of the duty cycle of the brake resistance measured by the brake resistance duty cycle- measuring circuit 9 is displayed on a display 12 by a display circuit 11 so that the duty cycle of the brake resistance 6 is known easily.
