Here we see this circuit diagram which is full H-Bridge using 4 power MOSFETs and 2 IR2111 high side driver ICs. That means this circuit is for making full bridge inverter which converts DC into AC. Power Supply Part We have +600V DC at top rail, written as +600V max. And ground (0V) at bottom. […]

Soft-Start Power Supply for Amplifier Loudspeakers
The proposed slow-start power supply circuit is specially designed for power amplifiers to ensure that the loudspeaker connected with the amplifier do not generate the loud and unwanted “thump” sound during power switch ON. This also implies that the power supply will safeguard or protect the loudspeaker from the sudden inrush current transient from the […]
Submersible Pump Start/Stop Circuit
In this post I have explained an automatic submersible pump start, stop circuit with dry run protection in order to implement an automatic ON/OFF switching of the motor in response to the high/low water levels of the overhead tank. Circuit Concept In one of the previous posts I have explained a similar concept which also […]
