Here I have tried to investigate a few enhanced triac based phase controller circuits which can be recommended for controlling or operating inductive loads like transformers and AC motors much safely than earlier traditional triac based circuit dimmer circuits. Using Triacs for Controlling AC Loads A Triac is a semiconductor device used for switching AC […]

Refrigerator Motor Soft Start Circuit
Refrigerators tend to draw appreciable amounts of current each time their compressor switch ON, and this could happen many times per day. A soft start circuit to the compressor motor could probably tackle this issue and help save electricity. The idea was requested by Mr. Naeem Khan. Technical Specifications I need your help regarding to […]
3 Phase Brushless (BLDC) Motor Driver Circuit
In this post I have explained how to make a simple 3 phase brushless DC motor driver circuit. The circuit employs the popular IRS2330 3-phase driver IC The presented idea looks simple since most of the technicalities is taken care of efficiently by the IC itself, it’s all about connecting the relevant pinouts with the […]
High Wattage Brushless Motor Controller Circuit
This versatile Brushless (BLDC) motor controller IC is featured to control any desired high voltage, high current, hall effect sensor equipped 3-phase BLDC motor with extreme accuracy and safety. I have explained the details in depth. Using the IC MC33035 The “hero” of the circuit is the single chip controller MC33035 which is a high […]
PWM Motor Soft Start Circuit to Prevent High Consumption during Power Switch ON
In this post I have explained an effective PWM motor soft start circuit which can be used for enabling heavy motors with a soft start and thus prevent the equipment from drawing dangerous high currents. Why a Soft Start High wattage motors such pump motors or other forms of heavy industrial motors tend to draw […]
