Oct 20, 2025 · The current waveform shows your triac triggering half wave. That is because the gate resistor is far too small, and there isn't enough voltage across it to generate sufficient …

Jul 3, 2023 · Hello everyone I've designed a circuit for dimming lamps with a triac (home automation). Everything was great and I also manage to produce a small batch, that got sold …

Aug 4, 2023 · I am looking for a way to make a "light dimmer" (actually controlling a heating coil) using a triac, where I can control the duty cycle of the AC based on a DC voltage. In searching …

Jun 25, 2019 · It is done all the time in thousands of applications, my air exchanger and portable fan uses same/similar shaded pole motor and uses a very basic Triac controller for setting …

Jun 7, 2022 · The reason the triac false triggers is because the voltage change is too fast dV/dt across it with the spike. Do you have a 1k gate-MT1 resistor, this lessens the triac's dV/dt …

Mar 11, 2009 · As usual the triac will be turned off at natural zero crossing (180 deg or 10ms). i.e., the triac is conducting for 0 - 180 and 180 - 360. So u r not at all controlling the voltage. So. …

Jan 23, 2015 · The reason i am not using a triac for phase angle control is that i am using the bulb as a heating element to effect PID control. That isn't so easy with a triac.

Nov 2, 2024 · Hi, In a dishwasher machine main board we have used 107NN0 triac for controlling ac loads such as valves, pumps, dispenser, etc. In about 2 to 3 percent of products sold to …

Feb 9, 2021 · Hello, sorry I know this is very basic but I want to understand the problem. I have an output on a boiler circuit board which feeds the ignition. Normally a small 550 watt ignition is …

Jun 1, 2009 · No. It can work. The TRIAC model you have pick is fine too. What you will need is an interface between the microprocessor I/O pin and the 24V system. This can be safely and …
