ABSTRACT:
In a current detector for use with a pulse-driven electromagnetic actuator drive circuit, a solenoid current detector is disclosed which operates by use of a solenoid current detection resistor to sample an instantaneous solenoid current value at intervals of a predetermined pulse voltage period, and calculates the average current value for the solenoid by calculation based on the sampled value.
