Switch Mode Power Supplies (SMPS) are widely used in electronic devices to provide efficient and regulated DC power. They are preferred over linear power supplies because of their high efficiency, […]
How to Make Dual Power Supply Circuit
The basic concept is that in a dual-supply circuit, “ground” is located halfway between the positive and negative supply voltages. Therefore, all that is required of us is that we […]
1.2 V to 32 V 10 Amp Adjustable Voltage Power Supply using LT1038
The LT® 1038 is a 3 terminal regulator which is specifically designed to handle an output current of 10 A at voltage levels ranging from over 1.2 V to 32V. […]
9V Power Supply Circuit using SCR with Auto Switch OFF
The low loss power supply circuit explained here employs an SCR that chooses taps on the secondary of the transformer based on the load current. Thus it helps to dissipate […]
High End Bench Power Supply with Variable Voltage/Current
The post explains a schematic design of a versatile, Hi-End work bench power supply whose output voltage and output current can be independently adjusted very finely, with high accuracy and […]
How To Design Simple Power Supply Circuit
In this post we try to understand how basic power supply circuit works and how to design regulated and unregulated power supply circuits. UNREGULATED POWER SUPPLY A single rail power […]
