DEVICE FOR DETECTING AN OUTPUT CURRENT OF AN INVERTER, CAPABLE OF DETECTING A CURRENT SUPPLIED FROM THE INVERTER TO A MOTOR

摘要

PURPOSE: A device for detecting an output current of an inverter is provided to accurately detect an output current to the motor without a phase delay.;CONSTITUTION: An inverter(312) generates a motor driving PWM(Pulse Width Modulation) signal. A resistor(320) for detecting a current is formed between the inverter and the motor and detects a supply current from the inverter to the motor without a phase delay. An insulation ADC(Analog to Digital Converter)(330) converts the voltage of both ends of the resistor for detecting the current into a digital signal and outputs the digital signal to a controller.;COPYRIGHT KIPO 2011
