LOAD CURRENT MEASUREMENT ERROR COMPENSATION METHOD OF ENGINE COOLING FAN MOTOR CONTROLLER

摘要

The present invention comprises a step of driving an engine cooling fan motor; a step of receiving an output voltage of an amplifier by using, as an input, a voltage caused by a load current flowing through the engine cooling fan motor; a step of calculating the voltage caused by the load current by using a voltage generated by an element deviation of the amplifier in the output voltage of the amplifier; and a step of obtaining the load current by converting the voltage caused by the load current.;COPYRIGHT KIPO 2014
