How to increase voltage without transformer

Last Updated on July 22, 2024

A Circuit used to increase the voltage output is known as voltage booster circuit, it can called as voltage step up circuit.

Here we use DC input and get DC output so that it can be termed as DC-DC Voltage boost converter circuit. It is used where load requires high voltage than Input or applied DC supply. Basic operation of this circuit is depends on the storage element and switching components.

Here we designed simple voltage booster circuit using transistor with Inductor.

Most booster circuit use Inductor (L) as a storage element, and it stores energy in the form of magnetic flux when the current flows through it and release it when the current flow is interrupted.

To make this operation continuous without stopping we can use any switching components (BJT, MOSFET) with timing control and by varying the switching speed we can get desired high DC Voltage than input DC.
