I want to develop a soft start system for the receiver. In real system, it is a power supply in the laboratory with a variable resistance value - hence programming the resistance R3 as a variable value determined by the voltage source.
The system to perform a soft start for the...
I have an angle grinder which have Maximum power of 950 watt
And my country provide 220 volt as voltage source
But it have one speed and i want to make a dimmer to control its speed.
I used this circuit but it provides at least 130 VAC
It make the machine rotate so fast
How can i make...
Hello! Please help me validate the electrical design and the set of the components.
The goal is to create removable modules that could switch the different types of payload:
1. DC MosFET module - switching and PWM of the 9-56V with 4A
2. AC MosFET module - switching and dimming (front and...
230v, 50Hz, two wires dimming circuit. Zero cross and phase angle are fine, but when triac is fired, due to missing neutral, and due to mains sine wave chopped by the phase control, then zero crossed is messed and the bulb goes disco blinking. If I power the circuit from separate mains source...
I made a TRIAC dimmer circuit using this reference,
it works very smoothly without snaps-on, but the C1 timing cap. has to be 100nF exactly, if it turns below some points like 85nF, then the lowest point of POT cannot turn off the TRIAC perfectly, for instance, in my work, I bought some 100nF...
