<p>When connecting a plurality of regenerative braking devices to a power supply device such as an inverter device, even if operations levels of the respective devices have parts tolerances, it is possible to uniformly operate the respective devices without lowering reliability. The regenerative braking device includes: a brake resistor (11) for consuming regenerative power; a switching circuit (12) for electrically connecting the regenerative power with the brake resistor (11); a voltage detector (14) for monitoring regenerative power; an operation level calculator (15) for outputting an operation level calculated in accordance with the electrical connection time of the brake resistor (11); a comparator (16) which compares the operation level outputted from the operation level calculator (15) to the monitor output of the voltage detector (14); and a drive circuit (17) which drives the switching circuit (12) according to the comparison result obtained by the comparator (16).</p> |
