CLOSED LOOP FEEDBACK CONTROL AND DIAGNOSTICS OF A TRANSPORT CLIMATE CONTROL SYSTEM

A closed loop feedback control and diagnostics system for a transport climate control system is provided. The closed loop feedback control and diagnostics system includes a plurality of source current sensors configured to monitor current received from a high voltage three-phase AC power source. The closed loop feedback control and diagnostics system also includes a plurality of compressor current sensors configured to monitor current drawn by an electrically powered compressor of the transport climate control system. The closed loop feedback control and diagnostics system also includes a controller configured to receive source current signals from each of the plurality of source current sensors, configured to receive compressor current signals from each of the plurality of compressor current sensors, and configured to control operation of the transport climate control system based on the received source current signals and the received compressor current signals.
