Jännitekorotus

Jännitekorotus, often translated as voltage boosting or voltage multiplication, refers to the process of increasing an electrical voltage. This is typically achieved through electronic circuits that utilize components like capacitors, inductors, and semiconductor devices such as diodes and transistors. The fundamental principle behind most jännitekorotus circuits is the storage and controlled release of energy.

One common method is using a charge pump circuit. In its simplest form, this involves switching capacitors between different voltage levels to effectively transfer charge and build up a higher voltage. Inductor-based converters, such as boost converters, operate on the principle of storing energy in a magnetic field. By switching an inductor and a diode, the energy stored can be released at a higher voltage. These circuits are crucial in many electronic devices where a battery or a lower voltage source needs to be converted to a higher operating voltage for specific components. Examples include portable electronics, power supplies, and even in certain industrial applications. The efficiency and maximum achievable voltage depend on the design and components used in the jännitekorotus circuit.
