Method of operating a lamp containing a fixed forward phase switching power supply |
摘要 |
A method of converting a line voltage to an RMS load voltage in a lamp includes performing fixed forward phase-control clipping of a load voltage with a phase-control clipping circuit that provides an RMS load voltage to the lamp and providing pulses at constant time intervals from a time-based pulse source. conduction in a three-terminal thyristor in the phase-control clipping circuit is triggered with the pulses from the time-based pulse source independently of the line voltage magnitude, wherein periods of conduction in the three-terminal thyristor define a conduction angle of the phase-control clipping circuit.
