Control Apparatus Using Variations In Conduction Angle As Control Command

摘要

A control apparatus using variations in conduction angle as control command, wherein a conduction angle modulation module of a traditional leading edge cutoff dimmer is arranged in parallel with a resistance module, so as to enlarge the minimum conduction angle of the leading edge dimmer. The modulation range of the conduction angle of the conduction angle modulation module may be set to a smaller range, so that the modulation range of the resistance module will not be uncertain due to different setting values of the variable resistance, whereby the circuit at load end can be identified readily and function mode switching facilitated to achieve the effect of multiplexing control.
