IGBT - Transistors with Excellent Performance Characteristics
Mitsubishi Electric is the leading manufacturer of Insulated Gate Bipolar Transistors (IGBTs), and now utilizes IGBTs in the converters and inverters of its 9700 Series UPS systems. These advanced, high-performance transistors provide a variety of intelligent features.
 High Ampacity Transistors (600A)
 High Speed Switching
 Low Control Power

Low Input Current Harmonics (THD)
 3% maximum (100% load)
 4% maximum (75% load)
 5% maximum (50% load)
(No additional filtering required)

Input Power Factor
 0.99 typical (0~100%)
 1:1 Ratio (No oversizing of generator)

Benefit of Lower Input Current
 Smaller upstream components (Transformers, Circuit Breakers and cable sizing)

Low Heat Loss / High Efficiency
Use of IGBTs transistor enables efficient high-speed switching (6kHz), thus reducing heat dissipation in the UPS.(Higher efficiency means lower cost per kilowatt to the customer.)

Extended Battery Life (0-100% Load Step)
 Supplemental current from the batteries is no longer required with the installation of IGBTs transistor in both the converter and inverter. Other UPS systems require assistance from the battery during step load conditions. The additional battery cycling results in decreased battery life.

Isolated Redundant System
 The 9700 Series is designed for isolated redundant applications.
 Lower cost to consumer, small footprint, less components.
 Different kVA sizes and different series can be used for greater flexibility of the overall system.
