Thyristor power control by ir remote pdf download

This coded data is executed by the microcontroller to deliver delayed firing pulses to the thyristor through optical isolation. Each time a button is pressed it sends a specific coded data in infrared range. This thyristor power control project is intended to manage the pace of an induction machine for example fans, by bringing into play a ordinary. The following treatment of bipolar junction behaviour assumes readers are familiar with basic semiconductor theory. Ir remote thyristor power controller electroschematics.

A common application of scrs is in the control of ac power for lamp dimmers, electric heaters, and electric motors. Controllable electronic load circuit for dc power supply 72. The microcontroller provides a delayed triggering control to triac through opto isolator interface. To control both polarities of the ac supply either two scrs had to be used, co n nected in antiparallel, or a single scr inside a full wave bridge rectifier ref. This thyristor power control project is intended to manage the pace of an induction machine for example fans, by bringing into play a ordinary television remote. R l represents the resistance of the load, r 1 limits the current, and potentiometer r 2 sets the trigger level for the scr. Microcontroller receives the coded data, processes it and then provides delayed firing pulses to thyristor with the help of optical isolation mechanism.
