Power electronics

Türkçe: Güç elektroniği

The field of converting electrical energy from one form to another (AC-DC, DC-DC) with semiconductor switches such as MOSFETs and IGBTs.

// EXPLANATION

It is found everywhere from PC power supplies to EV chargers and from data-centre racks to frequency converters. High-frequency switching allows small, efficient converters, at the price of harmonics and electromagnetic interference.

Power supply unit (PSU)The unit that converts mains AC into the low-voltage DC (12 V, 5 V, 3.3 V) a computer needs. Power factor correction (PFC)A circuit that shapes the current a power supply draws from the mains to follow the voltage, improving power factor and harmonics. HarmonicsDisturbing current and voltage components at whole multiples of the grid frequency (50 Hz), created by non-linear loads. RippleThe small alternating voltage superimposed on a DC output, caused by switching and mains frequency.
