Reduced Hysteresis Diac-Triac Phase/Power Control
This is a Reduced Hysteresis Diac-Triac Phase/Power Control circuit. This circuit is used to control from 5% to 95% of full load power. This circuit can decrease the hysteresis effect to a reasonable region. It can be done because this circuit uses second RC phase-shift network. Beside that, the second RC phase-shift network also extends …[Read More]
Diac-Triac Phase/Power Control without Hysteresis
Hysteresis in lamp dimmer or in other electric appliance might cause some trouble if you need a fine tuning, something like out of control. This is a circuit of Diac-Triac Phase/Power Control without Hysteresis. This circuit can eliminate the hysteresis effect. Here is the circuit: The initial condition of the timing capacitor is uniform because …[Read More]
This is circuit of soft light dimmer. This circuit uses the IGBT STGP10N50A and the TS555 timer as main components. Here is the circuit: The timer is triggered on the zero crossing voltage pulse. The time constant determined by C5/R14+R15 that is used to determine the conduction angle. The T2 – T3 inhibits the power …[Read More]
Dimmer Switch
This circuit is similar with our previous dimmer circuit, but the gate control is full-wave rectified using diode bridge. This circuit can be used to replace electric switch for your incandescent lamp, brushed motor, soldering iron or heater. Here is the schematic diagram of the dimmer switch: Please note that his dimmer switch can only …[Read More]
Dimmer Circuit
Light dimmer circuit is used to control the lamp for arbitrary brightness. This dimmer circuit work for incandescent lamp, not a fluorescent one. The dimmer circuit here work for both 110V and 220V AC. Here is the schematic diagram of the circuit: Dimmer Wiring Diagram The dimmer circuit is wired in series with the lamp, …[Read More]
