Dual power refrigerator |
摘要 |
A rotary-compressor control system for electric refrigerators using rotary compressors for cooling the inside of the refrigerators, in which a battery for feeding direct-current power, an inverter power section for converting direct-current (d-c) power from the battery into a low-voltage three-phase alternating-current (a-c) voltage, a low-voltage three-phase induction motor for driving the rotary compressor with the low-voltage three-phase a-c power obtained in the inverter power section, and a control circuit for controlling the inverter power section on the basis of a control command signal given from the outside, so that the rotary compressor is driven by the three-phase induction motor that operates with a low voltage of the order of battery voltage.
