The DC to DC converter circuit below uses an N-mosfet to produce a variable output of 3V and above depending on your input voltage. The maximum output of the circuit will be little lower than the input voltage. 3A TO 5A DC TO DC CONVERTER CIRCUIT VARIABLE DC TO DC CONVERTER CIRCUIT EXPLANATION Every mosfet […]

I want to talk about one of the major cause of heating in  H bridge and half bridge circuits which finally leads to failure. Though transistors in H bridge or half bridge may fail for many reasons, the most common cause of failure is “NO or SHORT DEAD TIME”. DEAD TIME OF H BRIDGE CIRCUIT From

Switch circuit which saves energy consumption by automatically turning off appliances connected to it either at day or at night. This switch circuit can be employed to reduce the energy consumption of fridges, air conditioners, lights, and many more appliances that you want to control their turn on time. The circuit is based on light

A circuit to double or step up the output of a small transformer so that it can power high voltage circuits. High voltages are at times needed but its a problem when we have to spend huge sums of money before we accomplish it. Am going to show you a high current circuit which can

Simple automatic change over circuit for homes and work places. Change overs are required whenever you are handling two or more power from different sources. In homes where inverters or generators are stand by power sources, it is advisable to use a change over system so that when your stand by power is in use,

Automatic temperature controlled fan using NTC.Sometimes, the systems that removes the heat can be disturbing with its noise. I want to show you a simple circuit that will remove heat from your electronic gadgets and systems that produces heat. The advantage of this circuit is that, the fan only turns on when there is heat
