Method of driving a power converter |
摘要 |
Disclosed is a method of driving a power converter which can simplify a charging sequence of a charge pump capacitor to reduce the time required to design the device without using a voltage protective circuit and optimum design required to determine the capacitance of the charge pump capacitor. A charging pulse signal for a capacitor (CP) is provided as an input signal from an external control device (EC) substantially simultaneously as a control power source (PS) is switched on to provide a predetermined control power source voltage (VPS). A driver circuit (DR20) outputs a control signal (VD) to turn on a transistor (Q2) in a pulse-like manner, starting charging the capacitor (CP). The charging pulse signal continues being provided after completion of the charging of the capacitor (CP) and stops being provided immediately before a PWM signal is provided.
