摘要 |
Phase angle detection techniques for phase-cut dimming lighting circuitry are disclosed. A phase-cut lighting driver circuit may include galvanic isolation circuitry having a primary and secondary side. The phase angle information of a phase-cut signal may be detected on the secondary side of the driver circuitry, and a microcontroller can create a dimming signal that adjusts the driver output power according to the phase angle information. In some embodiments, the phase angle detection techniques may be utilized to control the output of lighting driver circuitry, such as a phase-cut dimming LED driver. |
