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 highly sophisticated […]

SCR and Triac Gate Resistor Calculator
Here is a SCR and Triac gate resistor calculator along with the full detailed explanation. This will help users to calculate the right value of gate resistor for triggering an SCR or TRIAC safely. Calculator by homemade-circuits.com SCR / TRIAC Gate Resistor Calculator Gate Trigger Voltage (Vgt): Gate Trigger Current (Igt): Trigger Supply Voltage (Vs): […]
Triac Battery Charger Circuit
A triac based battery charger replaces a normal relay for automatically cutting off power to the battery very efficiently. In this post I have explained a simple a battery charger circuit using a triac auto shut-off facility. The circuit can be used for charging any high current, high AH types battery with a full-charge auto […]
SCR/Triac Controlled Automatic Voltage Stabilizer Circuit
In this article I have explained a relatively simple triac controlled automatic mains voltage stabilizer circuit, which uses logic ICs and a few triacs for controlling the mains voltage levels. Why Solid State Being solid state in design, the voltage switching transitions are very smooth with minimum wear and tear, resulting in efficient voltage stabilization. […]
Simple Triac Timer Circuit
Here’s a simple triac timer circuit which can be used for switching ON a particular device after a predetermined time, set through the given pot or the variable resistor. The shown circuit diagram of a simple triac timer can be understood by referring to the following explanation: How it Works The left hand side section […]
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 […]
