MOSFET Solutions for UPS & Inverters
MOSFETs manage battery charging, DC-bus conversion and inverter switching to keep critical loads powered during input interruptions.
How MOSFETs Maintain a Stable AC Output
During normal operation, the system manages the DC bus and battery charge. When input power is lost, the inverter bridge rapidly converts stored DC energy into a controlled AC supply for the protected load.
Grid Input
Incoming AC power supplies the load and supports battery charging during normal operation.
Charger & DC Bus
Conversion stages regulate the shared energy path between the grid, battery and inverter.
Inverter MOSFET Bridge
MOSFETs switch stored DC energy into a controlled alternating waveform.
Protected AC Output
Filtering delivers stable power to critical equipment when the grid is unavailable.
MOSFET Options for UPS and Inverter Stages
High-Voltage MOSFETs
For charging, auxiliary and inverter stages that need dependable voltage margin.
SiC MOSFETs
For higher switching efficiency and demanding thermal or power-density targets.
