Function of IGBT in UPS

The manufacturers of Uninterruptible Power Supplies face enormous contest as the UPS market is immensely competitive. Endeavors to uplift the performance and dependability of UPS units are going on constantly. A UPS can survive in the market if the components used in it can keep pace.

Spontaneous control, outstanding switching features and excellent reliability make IGBTs the perfect option today for medium and high-power UPS. These modules greatly enhance UPS performance, specifically in terms of proficiency, acoustic noise, shaped and weight.

In high capacity UPS where the inverter functions between 2 and 4 kHz, the prime benefit of the IGBT is simplification of transistor control (better reliableness). IGBT is comparable to the bipolar transistors in terms of efficiency.

In medium capacity UPS, which are often seen in computer rooms, the acoustic noise criterion makes it essential to eliminate the 50 or 60 Hz transformer and to attach an inverter operating at a frequency of 16 kHz, thus making the IGBT completely inevitable both because of the lessening in number of elements needed to control it and because of the increase in weight and aggregate dimensions.

Exceptional switching speed, effortless control and overload resistance of the IGBT make it a component of noteworthy interest in modern times.
