Title:
INTELLIGENT POWER MODULE AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2017/206385
Kind Code:
A1
Abstract:
An intelligent power module (1100) and an air conditioner. An HVIC (1101) of the intelligent power module (1100) has connection wire ends respectively connected to a three-phase upper bridge arm signal input end and a three-phase lower bridge arm signal input end, and a first port connected to a current detection end. The HVIC (1101) further has a PFC driving circuit signal output end. An input end of a self-adjusting circuit (1105) is connected to the first port, and a first output end of the self-adjusting circuit (1105) serves as an enable end of the HVIC (1101). A first input/output end, a second input/output end, a third input/output end and a fourth input/output end of a PFC switch circuit (1127) are correspondingly connected to the signal output end of the PFC driving circuit, a PFC low-voltage reference end, a PFC end, and a second output end of the self-adjusting circuit (1105), respectively. The self-adjusting circuit (1105) and the PFC switch circuit (1127), through different approaches, are capable of reducing the probability of erroneously triggering the intelligent power module (1100), enhancing the stability of the intelligent module (1100) in operation.
