Abstract

A brake control device for an elevator controls the voltage between the terminals of a brake coil (52) of the elevator, thereby controlling its brake operation. The brake control device comprises a transformer (25) having a primary coil (25a), one end of which is connected to a DC power supply, and a secondary coil (25b), a semiconductor switch element (27) connected to the other end of the primary coil (25a) of the transformer (25) and switching on or off the DC voltage applied to the transformer (25), a rectifier diode (31) for rectifying an AC voltage generated from the secondary coil (25b) of the transformer (25), and the brake coil (52) connected from the output of the rectifier diode (31) to the secondary coil (25b) through a normally-open contact point (33).
