mcus for online ups


Posted on Feb 7, 2014

With the increasing daily reliance on networked data systems, the need for failsafe backup of power supply systems is now essential. Uninterruptible power supply (UPS) technology, with a very high level of reliability, are now extensively used to provide this backup security. Renesas produces MCUs and highly efficient power semiconductor devices (

IGBTs and MOSFETs) designed for full-digital control system that delivers uninterrupted CVCF (Constant Voltage and Constant Frequency) output made possible by continuous online inverter. The key advantage of full-digital control for UPS systems is that all power conversion is handled by MCU, thus fewer total components are required comparing to a traditional analog system. This reduces overall cost and provides a more stable method of control.
