Spot welding needs very low voltage but very high current, that too for very short time, so now this whole thing is built around that idea. In this design we push big current in small time period for safely creating the required welding joint, done. Audio/Video Representation How the Circuit Works Now the circuit, it […]

32V, 3 Amp LED Driver SMPS Circuit
In this article I have explained a 32V, 3 amp SMPS circuit which may be specifically used as an SMPS 100 watt LED driver, rated with the same specs. The circuit of the proposed 32 V, 3 amp smps led driver may be understood with the the help of the following points: Circuit Operation The […]
12V, 5 Amp SMPS Battery Charger Circuit
In this article we study a simple flyback based converter design which is implemented as an SMPS 12V, 5amp battery charger power supply, without using a iron core transformer. How it Works The proposed 12V, 5 amp smps battery charger circuit employs a flyback converter topology which results in the required smps based high current, […]
220V AC to 56V DC SMPS Circuit for 48V Battery Charging
In this article we will try to understand how to build a 220V AC to 48 V DC SMPS circuit for charging all types of 48V batteries, using the nice little IC IR2153. However, since 48V battery will require a 56V DC, so we will rather discuss a 220V to 56 V DC battery charger […]
Convert SMPS into a Solar Charger
In this post I have explained how to convert smps into a solar charger circuit. The method will result in an extremely efficient and fast solar charging of the connected battery. SMPS Solar Chargers SMPSs have become very common nowadays and we find them being used in the form of AC to DC adapters wherever […]
SMPS 2 x 50V 350W Circuit for Audio Power Amplifiers
This article will illustrate a simple procedure to devise an unregulated 50V switching SMPS symmetric power supply of 350W. This unit can be substituted with the standard audio amplifier power supply to reduce expense and also the weight. The proposed power supply works as a half-bridge with no regulation.
