POWER FACTOR CORRECTION CIRCUIT MODULE AND MOTOR DRIVING CIRCUIT MODULE

摘要

The present invention relates to a power factor improving circuit module and a motor driving circuit module on which an inductor is integrated to a pattern or a lead frame within a module. The present invention comprises: a switch portion having a main switch switching an input power source and correcting the power factor of the input power source, and an auxiliary switch turned on prior to the turn-on of the main switch to form a transmission path of a surplus power source; an inductor portion having at least one inductor formed in a conducting wire on at least one circuit board to charge and discharge the energy of the input power source by the switching operation in the switch portion; and a control portion controlling the switching operation of the main switch and the auxiliary switch, wherein the switch portion and the control portion provide the power factor correction circuit module which is integrated into at least one circuit board.
