9V AC to 38V DC Voltage Tripler Circuit
This project is for simple 9V AC to 38V DC Voltage Tripler Circuit and it converts low AC voltage into higher DC voltage, also the input is 9V AC from transformer and the output is around 38V DC without load. Furthermore, it is easy to build as it uses common parts and therefore, it is […]
9V AC to 50V DC Voltage Quadrupler Circuit
Like our previous post on Half Wave and Full Wave Voltage Doubler Circuit this article explains a full-wave voltage quadrupler power supply circuit; the circuit converts a low AC voltage into a high DC voltage. For example, it converts 9 V AC into approximately 50 V DC. Therefore, the circuit multiplies the input voltage by […]
Half Wave and Full Wave Voltage Doubler Circuit
In many electronic projects, we need a higher DC voltage, but sometimes transformer gives low AC voltage; for example, a 9V AC transformer is common, therefore, we use voltage doubler circuit and this increases voltage without using high voltage transformer. Besides increasing the voltage, this circuit also converts AC into DC and also there are […]
AC Lamp Flasher Circuit using SCR
This AC Lamp Flasher using an SCR operates directly from the 230V AC mains, also it offers a simple, low cost design, making it suitable for decorative lighting, warning lamps and festival lighting. The circuit uses an SCR for switching and an RC timing network to control the flashing operation; as a result, the lamp […]
220V AC Live Detection and Interface Circuit
Handling 220V AC directly is very dangerous, but still we need to know mains is ON or OFF; so, this 220V AC Live Detection and Interface Circuit is useful as it solves this safety problem easily. This circuit safely senses the mains voltage and sends a clean logic-level signal, then an optocoupler provides isolation, keeping […]
