Pfc circuit and INVERTER circuit are two technique directions at present, the precedent that does not combine.
The utility model content
The purpose of the utility model aim to provide a kind of simple and reasonable, flexible operation, cost of manufacture low, be prone to install, intelligent frequency-conversion hybrid power module applied widely, to overcome weak point of the prior art.
A kind of intelligent frequency-conversion hybrid power module by this purpose design comprises pfc circuit and INVERTER circuit, it is characterized in that pfc circuit and INVERTER circuit are integrated in the module, and pfc circuit and INVERTER circuit are electrically connected.
Said pfc circuit and INVERTER circuit are electrically connected with control IC respectively.
Said pfc circuit and INVERTER circuit are electrically connected with control IC jointly.
Intelligent frequency-conversion hybrid power module also comprises rectification circuit, and rectification circuit is electrically connected with pfc circuit.
Said rectification circuit, pfc circuit and INVERTER circuit are integrated in the module.
Said rectification circuit, pfc circuit and INVERTER circuit are arranged on the same radiator.
The utility model is through being integrated in pfc circuit and INVERTER circuit in the module; Pfc circuit and INVERTER circuit are electrically connected; Can reduce the volume of radiator; Reduce cost of manufacture, the flatness of radiator requires only to become a module region requirement from three module region, has reduced the processing cost of radiator; Aspect installation, only need two fixing points just can, thereby simplified production technology, improved production efficiency.
The utility model both can be integrated in rectification circuit, pfc circuit and INVERTER circuit in the module; Also can be only with pfc circuit and INVERTER circuit package in a module; And rectification circuit is external; Its reason is that the technology maturity of rectification circuit is high, and cost is lower, and is little to the design influence.
After the utility model adopts above-mentioned technical scheme; Succinct package module; Simplified circuit design, peripheral circuit is simplified, because the distance of the connecting line between each power device of inside modules shortens; Externally disturb and reduce, also improved anti-jamming capacity simultaneously, reduced design difficulty, improved system reliability.
The utlity model has simple and reasonable, flexible operation, cost of manufacture low, be prone to install, advantage of wide range of application.
