摘要：Two or more electric devices (10,20) such as motors of a lift truck are poweredby a common battery, each being actuated by a separate SCR chopper circuit (12, 22). An

anti-coincidence circuit (30) senses an \"on\" actuation control signal to a SCR choppercircuit (12) of the lift truck drive motor (10) and inhibits any \"off\" actuation control signalto a SCR chopper circuit (22) of the lift pump motor (20) for a few hundred microsecondsbefore and a few hundred microseconds after the drive motor circuit (12) is actuated, toallow the battery to return to at least full open circuit voltage before the pump motorcircuit (22) is turned off.
