Thyristor dimmer

Thyristor dimmer

LED dimmer

Thyristor is a semiconductor device with single conductivity. During forward bias, the current starts from the A pole and passes through the P region to the N region; When reverse bias occurs, the current starts from the N region and passes through the P region to the A pole. When the input voltage is constant, the brightness of the light-emitting diode is controlled by adjusting the change in the control conduction angle.

Features: 1. Small size, light weight, easy to carry. 2. High efficiency, long lifespan. 3. No flicker. 4. High safety performance. 5. Wide adjustable frequency The working mode of the thyristor dimmer is divided into two working modes: constant current drive mode and constant voltage drive mode. The circuit of the constant current drive dimmer is composed of resistors R1 and R. A series resonant circuit composed of capacitor C1 and inductor L. When the AC power supply is applied to both ends of the dimmer, the voltage on the load RL cannot suddenly change, causing a change in the output current. In order to stabilize the output within a set range and achieve the predetermined brightness requirements, it is necessary to adjust the parameters in the circuit appropriately to achieve voltage stabilization There is a resistor R in the circuit of the constant voltage driven dimmer
