This is a simple blinking led circuit powered from 220V that can be used to mark special places or as voltage indicator. The voltage from the mains charges the capacitor through R1 resistor and D1 ...

This file type includes high-resolution graphics and schematics when applicable. For applications such as motor control or power supplies, it’s often necessary to know whether the ac line is at 120 V ...

This is a simple voltage driven inverter circuit which converts 12V DC signal to single phase 220V AC using power transistors as switching devices. This is a simple voltage driven inverter circuit ...

Sometimes, we might need an AC bulb flasher circuit that can blink a series of bulbs in a particular time interval for decorative purposes. By controlling the flashing time interval and sequence, we ...

Abstract: The direct drive circuit breaker by permanent magnet synchronous motor is a new servo technology that can drive the moving contact to complete the opening and closing operation along the ...
