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 […]
Switch Mode LED Driver Circuit using Transistors
Nowadays, LED is used everywhere, its used in display, in indicator and for decoration purpose also, but LED needs proper current, so if we connect LED direct to battery then it may get damage. So in this post we have designed a Switch Mode LED Driver Circuit using Transistors and this circuit is simple as […]
12V Boost Converter Circuit from 3.3V to 5V Supply
Nowadays, many electronic projects need higher voltage, however, the available supply is very low for example 3V or 3.3V batteries are common. But many circuits need 12V so, here we have designed a 12V Boost Converter Circuit from 3.3V to 5V Supply, as this circuit increases low DC voltage to high DC voltage and therefore, […]
