ABSTRACT:
A power conversion device contains an electronic circuit for sensing an output current characteristic of an output drive device. The characteristic of the current through the output drive device is sensed and communicated to a switching device for controlling a sensing current. The switching device is coupled to the output drive device and senses the output current of the output drive device. The switching device produces a sensing current proportional to the sensed output current. An internal resistance device is used for producing a sensing voltage. The internal resistance device is coupled with the switching device and receives the sensing current. The internal resistance device provides the sensing voltage from the sensing current proportional to the current through the output drive device.
