摘要： PROBLEM TO BE SOLVED: To provide a control device of an electric compressor capable of smoothly starting the electric compressor.
SOLUTION: In the step B, a system is set on standby for an interval, i.e., a predetermined time of several seconds (step S121) since an abnormality was repeated a plurality of times in the upstream side processing. Therefore, the states of the compressor and a motor can be stabilized. Next, the compression of a liquid is determined (step S122). In the determination of liquid compression, it is determined whether a torque required for compressing the liquid is unexpectedly increased or not by the liquefaction of a refrigerant to be compressed by the compressor. Specifically, it is determined whether the high-pressure side pressure value of the compressor is smaller than a predetermined pressure or not. When the high-pressure side pressure value is larger than the predetermined pressure, it indicates indirectly that the refrigerant is not liquefied.

摘要： PROBLEM TO BE SOLVED: To provide a controller for an electric compressor capable of realizing smooth start. SOLUTION: This controller for the electric compressor has a start controller 2. The start controller 2 has a shot pulse control part 5, a current detection part 6, and a rotor position inferring part 7. The shot pulse control part 5 sends a pulse signal having the minimum time latitude to an inverter 9 by an order from a driving control part 8 of a main controller 1 when starting from a condition in which an electric motor 3 stops. Consequently, current flows only during the minimum time in turn in each phase of the electric motor 3. The current detection part 6 acquires a value of current flowing in each phase by the pulse signal in the shot pulse control part 5. The rotor position inferring part compares values of currents acquired and stored by/in the current detection part 6 to infer a position of a rotor. After inferring the position of the rotor, the position information is transmitted to the driving control part 8 of the main controller 1 to control synchronous driving of a conventional synchronous motor corresponding to the position.
