Figure 1 Circuit schematic of mains cycle skipping controller, this controller skips a certain number of power cycles in between, to vary power to the heaters.. In this typical design, 10 full cycles ...

Power-control modules are circuits comprising devices such as silicon-controlled rectifiers, triacs, power transistors, and power rectifier diodes.

For the triac, the popular dimmer circuit is used for test, with output file Figure 4a along with corresponding schematic Figure 4b. The load is a typical 100-W bulb, and the RC-time constant ...
