Abstract

The invention provides an intelligent power module. The intelligent power module comprises a three-phase bridge driving unit, a PFC (power factor correction) simulation unit, a PFC driving unit, a functional protection unit, a three-phase bridge circuit, a rectifier bridge unit, a step-down voltage regulation unit, a logic-driving signal processor, a PFC switch unit and an alternating voltage detection unit. By integrating the three-phase bridge driving unit, the PFC simulation unit and the PFC driving unit, the intelligent power module is endowed with a PFC function, high power factor of theintelligent power module is realized, and burden of a power grid when the intelligent power module drives three-phase load is reduced.

Description

technical field [0001] The invention relates to the technical field of power correction, in particular to an intelligent power module. Background technique [0002] Intelligent power module is an advanced power switching device, which generally includes upper bridge arm drive components, lower bridge arm drive components and HVIC (high voltage integrated circuit high voltage drive control) chip, which is used to integrate detection functions such as overcurrent and overheating. Generally, the load connected to the intelligent power module is a nonlinear load, and its power factor (PowerFactor) is low. The intelligent power module cannot correct the power factor. If the power factor of the overall system needs to be improved, a power factor correction circuit (Power Factor Correlation, PFC) needs to be added to the periphery of the intelligent power module, which will lead to the complexity of the entire circuit, system size and cost. increase.
