voltage converter

A voltage converter is an electronic device that converts voltage to another voltage. It can be a direct current( DC) or alternating current( AC) voltage that is converted to another DC or AC voltage. A term used in power engineering is converter.

In terms of conversion capabilities, voltage converters are based on four basic principles:

  • AC to AC: Conversion of AC voltage to another AC voltage with higher or lower voltage or with higher or lower frequency. Circuits and devices that realize this function are converters or frequency converters. They convert an input AC voltage into an output AC voltage with a different amplitude and frequency.
  • AC to DC: Conversion of AC voltage to DC voltage, i.e. Alternating Current (AC) to Direct Current (DC). These electronic circuits are rectifiers. They convert AC voltage to DC voltage of any voltage magnitude.

    Principles of voltage converters

  • DC to AC: Conversion of DC voltage to AC voltage, i.e. Direct Current (DC) to Alternating Current (AC). These devices, which are used in photovoltaics and other applications, are inverters. The DC voltage is converted into AC voltage in order to feed it into the power grid, as in photovoltaic systems.
  • DCto DC: Conversion of DC voltage into DC voltage, i.e. Direct Current (DC) to Direct Current (DC). These DC to DC converters first convert the DC voltage to an AC voltage, transform it to the desired voltage, and then rectify it.

Some of the above circuits can be implemented using voltage dividers, transformers or simple control circuits with voltage stabilization circuits.
