摘要： It is checked whether or not a primary-side voltage (V1) of a remote shutoff breaker (32) and a secondary-side voltage (V2) thereof become a rated voltage after a commercial power system is recovered from a blackout. Next, when both primary-side voltage (VI) and secondary-side voltage (V2) become the rated voltage, a contactor (33) is actuated to interconnect a home power system with the commercial power system. Hence, charging of the home power system without causing a user to notice such a charging upon recovery of the commercial power system from a blackout can be prevented. As a result, the safety for the user can be ensured.

摘要： An object is to prevent a motor and an inverter from being damaged due to the flow of a large current when a compressor is heated by supplying a high-frequency AC voltage to the compressor. The heat pump device includes an inverter control unit outputting PWM signals to an inverter 9; a current detection unit 20 detecting a current value flowing in the inverter 9 and outputting the current value after reducing a current value having a first frequency or higher in detected current value; and a drive-signal stop unit 41, 42 that, when the current value output from the current detection unit 20 is equal to or larger than an interruption level, stops output of PWM signals to the inverter 9. Particularly, the inverter control unit generates a voltage command value such that the voltage command value becomes a value equal to or larger than a lower limit determined according to the first frequency and generates PWM signals based on generated voltage command value and a carrier signal, thereby causing a voltage output time to the motor to be a predetermined time or longer.

摘要： An object of the present invention is to maintain a heating amount constant when a compressor is heated at the time of shutdown of the compressor, regardless of the influences of production tolerance and environment variations. An inverter control unit 10 causes an inverter to generate a high-frequency AC voltage having a de-energized section in which a voltage applied from the inverter to a motor is zero between a section in which the voltage is positive and a section in which the voltage is negative. At this time, the inverter control unit 10 detects a value of a current flowing to the inverter in a detection section residing from immediately before a start of the de-energized section to immediately after an end of the de-energized section, and causes the inverter to generate a high-frequency AC voltage adjusted according to the detected current value.
