Title: Rising time shortening circuit for high power factor converter
Inventor: OTAKE TOSHIO
IPC: H02M7/12
Filed: 1992-09-25
Abstract: PURPOSE:To shorten rising time of high power factor converter by inserting a capacitor between a start-up capacitor and the primary winding of an inductor while furthermore inserting a diode for blocking counter flow to the capacitor thereby decreasing the capacitance of the start-up capacitor. CONSTITUTION:A start-up capacitor 33 is initially charged with a current fed through a resistor 32. Capacitance of the start-up capacitor 33 is decreased in order to decrease a time constant RC. When supply voltage to an IC 4 exceeds 10V, the IC 4 begins to function thus requiring more current than that being fed through the resistor 32. Consequently, bootstrap winding Ns in an inductor 3 begins to function to store energy in a capacitor 35 through a diode 34. Energy is further stored in the start-up capacitor 33 through a diode 36 and subsequently fed to the IC 4 thus sustaining the function thereof.
