  • Patent number: 10439431
    Abstract: A method reduces inrush currents in a transformer-less rectifier UPS system when an input circuit breaker of the UPS system is closed from an open position. The circuit breaker is coupled between an AC power input and an AC input of a rectifier of the UPS system and a DC output of the rectifier is coupled to a DC bus of the UPS system. Before the circuit breaker is closed, the DC bus is charged to a DC voltage having a level that is equal to a peak AC voltage level of a line-line AC voltage of AC input power to the UPS system. The rectifier is operated as an inverter to provide an AC output voltage at the AC input of the rectifier that is equal to an AC voltage at the AC power input and when it is equal, the circuit breaker is closed.

  • Patent number: 10439392
    Abstract: A serial acquisition of multiple power sources via one or more multiplexers which is circulated in many corridors of a multi-port system with a resonant engine. A controller manages multiplexer/switches connecting a first plurality of DC power sources and an auxiliary DC power source to a circulator. A multiplexer/switch revolves each source of power to inverters for DC-AC conversion. Reciprocity of power sharing and management of signal routing between input power sources can be performed to maintain discrete operation between the input/output power sources and individual power inverters for precise load power delivery. Regenerative power from a motor load can be directed to “recharge” an input power source. The resonant engine applied to each power source provides a constant conduit of energy during off-operation/cycles.
