IGBT Explained

IGBT’s (insulated-gate bipolar transistors) are used in modern Uninterruptible Power Supplies (UPS) combining high efficiency with fast switching whilst keeping the frequency output without narrow tolerances. Stable seamless electrical power supply.

IGBT provide extremely low voltage distortion and improves the power efficiency especially when supporting IT equipment and Computer/server loads. IGBT are mostly used in Static UPS systems that have battery back up autonomy for Power Continuity.

An IGBT is actually a three-terminal power semiconductor device that operates as an electronic switch and within a UPS you will find many of these, dependent on the size of the UPS.

IGBT act in a similar way electronically as a Thyristor, although IGBT are superior and faster. Inverters can be sized smaller in UPS’s when IGBT’s are used within the UPS design.

IGBT’s are a functional part of a UPS and are fully integrated into Mother Board operations. The life of IGBT’s depend on the load and environment of the UPS. They don’t last forever.

We suggest that any IGBT which has not been replaced after 7 years should be upgraded with new IGBT’s.

As with any electronic components, IGBT’s have a shelf life and do NOT last forever.

IGBT do require regular replacement. If the IGBT fails then your UPS will fail. Always keep your UPS DUST free and in a cool air conditioned environment

Build up of dust and air borne debris can interfere with the operation of a UPS and cause over heating leading to a FIRE

KEEP ALL UPS DUST FREE & REPLACE IGBT & CAPACITORS REGULARLY
