Title:
INTELLIGENT POWER MODULE AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2018/166074
Kind Code:
A1
Abstract:
An intelligent power module (4100) and an air-conditioner. The intelligent power module comprises a power drive circuit, an adjustment circuit and a current sampling circuit. The current sampling circuit is connected to the power drive circuit, and is used for collecting a real-time current value of the power drive circuit and converting same into a real-time voltage value; and the adjustment circuit is respectively connected to the current sampling circuit and the power drive circuit, and is used for generating a pre-set voltage value and comparing the pre-set voltage value and the real-time voltage value, so as to generate a switch control signal for transmission to the power drive circuit. The air conditioner is realized based on the intelligent power module. The magnitude of a pre-set current value can be set according to an environment where an intelligent power module or subsequent drive circuits thereof are located, so that the problems of a bad user experience brought about by the premature stoppage of work and increased costs brought about by an increase in a current margin are avoided.
