Abstract
A drive equipment has an AC motor and a self-commutated static converter for transmitting electrical power between the motor and a network for driving and braking the motor. The equipment has braking resistors, each of which is connected between a DC terminal and an AC terminal of the converter. Connected in series with each braking resistor is a thyristor which acts to control the current through the braking resistor.
