Technical description

  • The firmware controls the SSR-based power path and maintains UPS operating states, including switching order and reaction to supply availability changes.
  • The controller logic covers switching conditions, start/stop sequence and reaction to power availability changes.
  • SSR control moves part of the hardware-safety responsibility into firmware: state order, delays and interlocks directly affect the load.
  • The power path consists of the input supply, UPS/battery section, SSR switching stage, load and STM32 control logic.
  • The code is part of a power-control system, so a wrong program decision may cause an incorrect power-path switch.
