Mains Voltage Stabilizer Circuits
These circuits were drawn for a person in Africa. See the thread here… stabilizer circuit. They were not tested by me, but are quite close to a practical design.
Stabilizer Step up 230V AC 500VA
This circuit is a design i did, not tested by me as yet. It can Stabilize Mains voltage to [...]

2N2646 based Voltage controlled SCR Pulser
A Center tap 50Hz Step Down Transformer with two diodes is used to get a train of Positive Sine Pulses at 100Hz which is applied to Q6 base via R51. 2N2646 is a unijunction transistor(UJT) in a TO-18 metal package. The control voltage or voltage proportional to error is fed to R56-Q3, The UJT drives [...]
AC-AC-SSR Solid State Relay
This is a AC Control Input AC Output SSR Solid State Relay. When a Process Controller has an AC output or a system generates an AC signal of above 100V AC to signal the load to turn on, this device can be used. A BTA40-600 and MOC3041 are used in this. A high voltage plastic [...]
Normally Closed AC SSR
This is a Normally Closed PCB Mount SSR. That means when DC Control input is low, the triac is ON, the output passes the load current to turn on small heater-motor-lamp or a bigger contacter-drive etc.
When input DC is high the output is OFF. This is also Optically Isolated from Mains. A Microcontroller output which [...]
