CONTROLLER FOR LOAD CIRCUIT |
摘要 |
A vehicle propulsion motor control apparatus includes a motor current regulating chopper apparatus and a free wheeling diode in the motor circuit. It is desired that the chopper apparatus not be commutated OFF when the free wheeling diode is conducting motor current to prevent damage to the free wheeling diode. A current detector is provided to prevent commutation of the chopper apparatus in response to sensing a current flow through the free wheeling diode. |
