坚持就是胜利英语摘要：Rever pha-controlled dimming of -powered load is accomplished by switching power to the load on and off during each half cycle. In one embodiment of the prent invention, power is switched on when line voltage is substantially equal to load voltage and off at a lected time later in the half cycle or at any time that the voltage across the switch exceeds a predetermined value. Preferably, switching is accomplished with a pair of field effect transistors. The load preferably includes a capacitor from load hot to neutral. The prent circuit permits quiet dimming of incandescent lamp loads without the need for complex circuitry. It is particularly well adapted for dimming low voltage lamps using a solid state transformer.
