Power Supply Circuits

A Tesla coil is a device that generates high voltage and low current energy, this mini tesla coil circuit is a scaled down version of the original tesla coil. You may light up little things or produce tiny sparks using mini tesla coils, which are usually powered by a 9V battery or another low voltage […]

A buck converter circuit well known as as a step down converter is a workhorse in electronics. It takes a higher DC voltage and reduces it to a lower DC voltage. Imagine it like a voltage reducer valve for electricity. They are commonly used for laptops and phones because they efficiently bring down battery voltage […]

Have you ever tried to use a toy that needs less power 3.3V with a charger that gives too much power 5V? A 5V to 3.3V converter circuit is like a special adapter. It takes the strong power 5V and weakens it 3.3V to the perfect level for your electronic device. This is useful when […]

Converting 3V to 5V involves using a circuit called a boost converter. Boost converters take a lower voltage input and increase it to a higher voltage output. In this case, it would take the 3V from your source like a battery and bump it up to 5V to power your device. Circuit Working: Parts List: […]

If you have a single AA battery 1.5V but your gadget needs more power 10V to work. A 1.5V to 10V boost converter circuit is like a mini power station. It takes the weak 1.5V from the battery and turns it into a stronger 10V, making your gadget happy. These circuits are handy for electronics […]

If you have a device that needs just the right amount of battery power DC voltage to work safely. A simple DC cut off circuit acts like a guard for that device. If the battery gets too weak low voltage, the circuit cuts off the power to protect the device. If the battery gets too […]
