Simple soft press switch using an NPN transistor, N mosfets, and either a P mosfets or a relay depending on your load. The soft press switch in this circuit is similar to our computer, monitor and some phone switches. I like it most because of its durability and nice look when fixed. SOFT PRESS SWITCH […]

H Bridge circuit is the arrangement of electronic switches in a pattern that forms the letter ”H” during switching. The switches may be bipolar transistors, Mosfets, IGBTs, etc.  These switches are controlled by logic signals in such a way that the four arranged switched connected in “H” turns on diagonally as shown below: In H

We are going to step down high DC voltage to low DC voltage using simple approach. This circuit can convert 18V – 300V DC to 12V, 24V, 36V, 48V and any stepped down voltage that you want.The circuit can be used in inverter systems to step down the system voltage to a level that is acceptable for

The circuit below will make the outputs from your inverter, SMPS and all PWM circuits stable. This is a simple feedback circuit for all PWM inverters and converter circuits. The circuit shows how to use optocouplers or photo transistors for feedback operations. Photo transistor / optocoupler feedback circuit for PWM converters. Feedback control circuit using
