Abstract
PURPOSE: To magnify regenerative, effective speed, by suppressing the jumping voltage of a filter condenser by inserting a damping resistance into a regenerative braking circuit and by simultaneously closing a switchgear by the short instructions of a short device.
CONSTITUTION: A short device 12 and a switchgear are brought to opening conditions, and a damping resistance 11 is inserted in series into a main circuit, thus effectively working regenerative braking. A comparator 20 functions to generate output, a pulse shaping circuit 21 operates by the output, the making instruction pulses of the short device 12 are put out and the short device 12 is closed. A delay circuit 22 receives the output of the comparator 20 at the same time as the closing of the device 12 and works to generate continuous pulse output, and the switchgear 6 is brought to a short condition. Thus, the jumping voltage of a filter condenser generated due to the shorts of the damping resistance 11 is absorbed to a damping resistance 5 because the switchgear 6 is brought to the short condition at the same time as the making of the short device 12, and the voltage rise portion can sharply be suppressed.
