FIXED REVERSE PHASE SWITCHING POWER SUPPLY WITH TIME-BASED PULSE TRIGGERING CONTROL |
摘要 |
A phase-control power controller that converts a line voltage to an RMS lo ad voltage includes a fixed, reverse phase-control clipping circuit that perfor ms phase- control clipping of a load voltage to provide an RMS load voltage. A conduction angle of the phase-control clipping circuit is defined by a time-based pulse sourc e that triggers conduction in the phase-control clipping circuit independently of line volta ge magnitude. The phase-control clipping circuit includes a transistor switch whose gate receives positive polarity signals from the time-based pulse source to trigger conduction of the phase-control clipping circuit. The power controller may be in a voltage conversion circuit that converts a line voltage at a lamp terminal to the RMS load voltage usable by a light emitting element of the lamp.
