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 […]
4.5 V, 6 V, 9 V , 12 V Power Supply Circuit
THIS little power supply supplies a range of switch selectable output controlled voltages from 4.5 to 12 volts, selectable by a switch. The supply provides up to 400 mA and […]
Ten Channel Touch Switch Circuit
This ten channel touch switch circuit can be used to generate ten individual on/off outputs in response to the touching of ten respective touch pads. Touch switches are available in […]
Adjustable Power Resistor Circuit
A serious problems came across when examining power supplies is the availability (or nonavailability) of a suitable load. Generally, the issue is sorted out by a lash-up of resistors which, […]
