In this post I have explained about a simple surge voltage protector circuit using a fuse and a triac crowbar circuit and also learn the method to record and measure […]
Voltage Control and Protection
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 […]
Simple Refrigerator Protector Circuit
This simple refrigerator protector circuit is actually a delay ON timer circuit which makes sure that whenever a power failure occurs or in case abrupt power fluctuations take place, the […]
PWM Controlled Voltage Stabilizer Circuit
In this post I have explained how to make a high power 100V to 220V H-bridge mains voltage stabilizer circuit using automatic PWM control. The idea was requested by Mr. […]
Power Factor Correction (PFC) Circuit – Tutorial
In this post I have explained the different methods of configuring a power factor correction circuit or a PFC circuit in SMPS designs, and explains the best practice options for […]
Automatic Voltage Regulator (AVR) Circuit
An automatic voltage regulator circuit is quite well used where Voltage supply is only 120VAC. Many gadgets can operate good at 220V Ac that is why Voltage regulation is needed. […]
