| Title: |
Forward/Reverse Hybrid Switching Power Supply With Time-Based Pulse Triggering Control |
| Abstract: |
A phase-control power controller that converts a line voltage to an RMS
load voltage includes a fixed phase forward/reverse hybrid phase-control
clipping circuit that performs 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 source that triggers
conduction in the phase-control clipping circuit independently of line
voltage magnitude during time periods that span polarity changes of the
load voltage and that are separated by intervals when conduction is not
triggered. 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.
