Providing modern electronic devices with a diet of healthy power is not straightforward. Small AC-connected equipment often uses a capacitor-input filter following a half- or full-wave rectifier.

During development of a battery-powered device, the flexibility that a variable power supply provides can be very useful. You can set the voltage to simulate a fully charged or partially discharged ...

Figure-1 shows the schematic diagram of the device. P1 is used to connect the 220V-AC input and the ON/OFF switch to the circuit. C1 is used to reduce the AC voltage. The value of the C1 also ...

AC loads are everywhere around us and at least home appliances are powered using 220V/110V AC. Many industrial equipment are also powered by the single-phase AC voltage. Therefore having full control ...
