Line-powered, phase-control circuit |
摘要 |
A line-powered phase-control circuit includes a source of rectified voltage. An inductance is responsive to the rectified voltage. A switching transistor has a conduction path connected in series with the inductance at a junction. One plate of a charging capacitor is connected to the inductance and the rectified voltage charges the charging capacitor through a first diode. A switch mode power supply includes a transformer having a primary winding connected between the junction and the plate of the charging capacitor. A second diode is connected between the inductance and the junction.
