Triac Phase Control using PWM Time Proportional

A triac phase control using a PWM circuit can be useful only if it’s implemented using a time-proportional format, otherwise the response could be haphazard and inefficient. In a few of of my earlier articles as given below: Simple Remote Controlled Fan Regulator Circuit Push Button Fan Regulator with Display Circuit Dimmer Circuit for LED … Read moreTriac Phase Control using PWM Time Proportional

Triac based SPDT Relay Switch Circuit

The post details a simple solid state triac SPDT relay circuit, using an optocoupler and a couple of triacs, which can be used as an effective replacement for mechanical relays. The idea was requested by “Cypherbuster”. Introduction In one of the other posts we learned how to make an DPDT SSR using mosfets, however this … Read moreTriac based SPDT Relay Switch Circuit

Solid-State Inverter/Mains AC Changeover Circuits Using Triacs

The post explains 2 simple concepts for making solid-state triac based Inverter/mains AC changeover circuit, the idea was requested by Music girl. Technical Specifications I would like to replace the SPDT relay with 2 scr’s. Would you consider a circuit to replace those changeover relays? I believe a relay would need to handle 60 amps … Read moreSolid-State Inverter/Mains AC Changeover Circuits Using Triacs

High Current Triac BTA41/600B – Datasheet, Application Note

Triacs are one of the most important active electronic components which are exclusively used for power switching applications, these devices are especially suited to AC mains loads, and are able to switch large currents consistently. Triacs are the solid state replacements to mechanical relays, and come configured as static relays. The modern triacs today are high sophisticated … Read moreHigh Current Triac BTA41/600B – Datasheet, Application Note
