Abstract

The invention discloses a temperature control device and method of a power device and electrical equipment, and the device comprises a semiconductor thermopile unit which detects the temperature of the power device, and obtains the current temperature of the power device, an acquisition unit used for detecting the current of the power device to obtain the current of the power device, and detectingthe voltage of the power device to obtain the current voltage of the power device, a control unit used for generating a first control signal capable of controlling the refrigerating capacity of a semiconductor thermopile unit according to the current temperature and the current current and the current voltage in two adjacent periods, and the semiconductor thermopile unit used for adjusting the refrigerating capacity of the semiconductor thermopile unit under the control of the first control signal so as to control the current temperature of the power device. According to the scheme, the heatdissipation difficulty of the power device in the electric controller of the electrical equipment can be reduced, and the heat dissipation performance is improved.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a temperature control device, method and electrical equipment of a power device, in particular to a control device, method and electrical equipment for precise temperature control of IGBT based on thermoelectric refrigeration. Background technique [0002] The demand for miniaturization and ultra-thinning of electrical equipment (such as air conditioners) has become a trend in the development of next-generation air conditioners. Similarly, the electric controller of the air conditioner also needs to be miniaturized in order to realize more functions in a limited design space. In the electric controller of the air conditioner, good heat dissipation of power devices such as IGBT (Insulated Gate Bipolar Transistor, that is, insulated gate bipolar transistor) has always been a difficult problem to solve. [0003] The above content is only used to assist in u...
