PHASE ANGLE MEASUREMENT OF A DIMMING CIRCUIT FOR A SWITCHING POWER SUPPLY |
摘要 |
An example controller for a switched mode power supply includes a zero-crossing detector and a drive signal generator. The zero-crossing detector is coupled to generate a zero-crossing signal representative of a phase angle of a dimmer output voltage for a half line cycle of the power supply. The drive signal generator controls switching of a switch to regulate an output of the power supply in response to a feedback signal representative of the output. The drive signal generator further controls switching of the switch to adjust dimming of the output of the power supply in response to the phase angle indicated by the zero-crossing signal.
