DIRECT-CURRENT VOLTAGE CHANGER INCORPORATING PULSE-SWITCHING SURGE FILTERS AND BUILT-IN MICROCONTROLLER Russian patent published in 2006 - IPC H02J7/34 

FIELD: no-break power supplies for important industrial and military power consumers.

SUBSTANCE: proposed device has pulse-switching surge filters of main and stand-by supply mains, current sensors of main and stand-by channels, comparators of main and stand-by channels, inverter control signal disabling circuits of main and stand-by channels, real-time watch of inverter control system of main and stand-by channels, nonvolatile memory of inverter control system of main and stand-by channels, stand-by power supply of built-in microcontroller inverter control system of main and stand-by channels, and original algorithms (monitoring voltage level across main and stand-by mains, detecting voltage level across main and stand-by mains within admissible voltages, regulating load voltage when voltage level across main and stand-by mains is within admissible values) implemented in microcontroller of inverter control system of main and stand-by channels.

EFFECT: enhanced resistance to pulse-switching surges penetrating from supply mains, ability of protecting device equipment against load short-circuits; enlarged functional capabilities.
