DIY Simple DC Voltage Booster Circuit (3.7v to 200v)

DIY Simple DC Voltage Booster Circuit (3.7v to 200v) - No PCB!

Looking to boost your DC voltage without a complicated PCB? This video is for you! We'll guide you through building a simple yet effective voltage booster circuit that can take your 3.7v battery power all the way up to 200v!

DC-to-DC boost converter circuit is a circuit that can convert a DC voltage into a larger DC voltage.

So, for example, you may be able to convert a 1.5V dc voltage into 50V.

DC-to-DC converter works on the principle of an inductor primarily and a capacitor. When fed DC power, the inductor acts as an energy storage device for current. As long as DC power is supplied to it, it builds up current through the coils as well as a magnetic field around itself. When the DC power is turned off, the magnetic field collapses and all the current that the inductor charged up gets dumped across to the capacitor. As the DC power gets turned on and off in the circuit, which we will do through a pushbutton switch, the inductor stores up more current and dumps it across the capacitor each time. This is why the voltage across the capacitor increases each time we do this until it reaches its peak.

The amount of voltage that the output will increase depends upon a number of factors including the value of the inductor, the maximum voltage storage of the capacitor, the switching speed, and the DC input voltage of the circuit.

We won't go to in depth mathematically about each relationship but will show how these variables relate to the amount of voltage increase there will be.

In this circuit, we will use a manual pushbutton to switch the DC value on and off.

In a more advanced, real-life circuit, you would use a transistor instead of a manual switch, as this gives more precision and control over the circuit. Unlike manual control, a transistor can switch on and off much faster, in the order of microseconds, and give much more precision. A microcontroller would control the transistor and it could be coded to turn the transistor on and off at set intervals. Under such control, the output voltage would be able to be calculated precisely and the code could be written so that these bursts of DC voltage occurred at desired times.
