Jännitekorotin

Jännitekorotin, also known as a voltage booster or step-up converter, is an electronic circuit that increases a lower DC voltage to a higher DC voltage. This is achieved through the use of an inductor, a switching element (typically a transistor), a diode, and a capacitor. The fundamental principle relies on storing energy in the inductor during a charging phase and then releasing it rapidly to increase the voltage.

In a typical jännitekorotin circuit, a switch rapidly turns on and off, controlling the flow of current through the inductor. When the switch is on, current flows through the inductor, building up a magnetic field and storing energy. When the switch turns off, the magnetic field in the inductor collapses, inducing a voltage spike that is higher than the input voltage. This spike is then rectified by a diode and smoothed by a capacitor to provide a stable higher DC output voltage.

Jännitekorotinta are widely used in various electronic devices where a higher voltage is required than what a battery or power source can directly supply. Examples include portable electronics like mobile phones and laptops (for charging or powering specific components), LED lighting systems, electric vehicles, and power supplies for various industrial applications. Their ability to efficiently convert lower voltages to higher ones makes them essential components in modern electronics design. The efficiency of a jännitekorotin can vary depending on its design and operating conditions, but modern circuits can achieve high levels of efficiency, minimizing power loss.
