Uninterruptable Power Supplies (UPS)

Uninterruptible Power Supply (UPS) systems are widely used to safeguard power supply for critical components in a myriad of applications ranging from telecommunications and data centers, to various industrial facilities. These systems ensure reliable voltage supply by providing a filter function in addition to compensating for short-term power outages from the grid.

ON Semiconductor provides a wide and deep portfolio of high performance discrete devices, including power MOSFETs, IGBTs, SiC Diodes, High Voltage Gate Drivers (HVICs), Interleaved PFC Controllers, Flyback & Forward PWM Controllers with Integrated MOSFET, high power modules, and isolation for signal and gate drive, to address the demanding requirements of a diverse range of low, medium, and high power uninterruptible power supply (UPS) designs.

IC design to achieve high insulation voltage and high noise immunity, characterized by high common mode rejection.
These devices offer a 1,414 V peak working voltage to permit the device to directly drive medium power IGBTs.
The use of P-channel MOSFETs at output stage enable lower dynamic power consumption per cycle during switching
that current solutions.
High Performance Optocouplers ON Semiconductor's 3.3V/5V high-speed logic gate optocouplers support isolated communications between
systems without conducting ground loops or hazardous voltages. Each high-speed optocoupler utilizes
ON Semiconductor’s patented coplanar packaging technology, Optoplanar® and optimized design. This achieves
excellent noise immunity, characterized by high common mode transient immunity and power supply rejection
specifications, and allows these devices to operate in noisy industrial environments (100% better than our
closest competitors).
