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 […]
