ST’s MOSFET technologies for uninterruptible power supplies
Introduction
The UPS (uninterruptible power supply) is gaining ever increasing importance in office and
industrial environments, because it preserves the information and business operations from
power supply failure or blackout. Thanks to its technological improvement, it is now suitable
both for big customers and for individual users. The right designer’s choice about MOSFETs
in DC-AC (H-bridge converter) section enhances the overall system performance: THD,
power and thermal management and short-circuit ruggedness. In this article, ST’s MOSFET
technologies are described, highlighting their benefits as well.
