摘要： A compressor and an air-conditioner having the same are disclosed. A compressor application voltage is detected, and the air-conditioner is operated in a pre-set operation mode according to the detection result, or the air-conditioner is operated in a pre-set operation mode in a certain time domain, thus continuously operate the compressor. Or, a compressor temperature or an ambient temperature is detected to operate the air-conditioner in a pre-set operation mode or operate the air-conditioner in a pre-set operation mode within a certain time domain, thus continuously operate the compressor. Accordingly, the compressor can be operated in a particular operation mode within a certain time slot regardless of an ambient temperature, whereby an excessive cooling operation cannot be performed at night to thus provide an agreeable cooling operation and reduce noise. The compressor is prevented from being stopped due to a low voltage, and because power of the compressor is not repeatedly turned on or off, power consumption can be reduced and reliability can be improved.

摘要： A braking controller of a three-phase permanent magnetic brushless DC motor for directly driving a screw pump includes a detection circuit for detecting power supply states of the three-phase permanent magnetic brushless DC motor and a braking circuit for controlling the braking startup according to the power supply states of the three-phase permanent magnetic brushless DC motor. When the motor is supplied with power, the braking circuit is cut off. When the motor is not supplied with power and the screw pump drives the motor to reverse, the braking circuit starts up.

摘要： A control for a refrigeration system serviced by a special pulse width modulated compressor (30) coupled to a condenser (32)and evaporator (42). The system can be of the distributed type wherein the condenser (32) and compressor (30) may be coupled to service a group of adjacent refrigeration cases, wherein each case would have its own evaporator (42). A controller (52) is coupled to a load sensor (58) for producing a variable duty cycle control signal (54) in which the duty cycle is a function of demand for cooling. Moreover, fuzzy logic technique may be utilized in order to provide self adaptive tuning control for the system.
