Abstract: A dual input power supply system/method providing uninterruptable power to a protected load device (PLD) is disclosed. The system includes hybrid switch devices (HSD) comprising semiconductor and relay/contactors that minimize the OPERATE/RELEASE times associated with switchover from a primary power source (PPS) to a secondary power source (SPS). An operate/release controller (ORC) monitors the condition of power provided by the PPS and SPS and determines the optimal transfer time to activate the HSD and switch between the PPS and SPS based on the PLD configuration. Use of the HSD in conjunction with the ORC permits a wide variety of series permutated AC/DC primary (PPS) and secondary (SPS) power sources, EMI snubbers (EMS), bridge rectifier diodes (BRD), AC-DC converters (ADC), and DC-DC converters (DDC) to service the PLD, while simultaneously reducing storage capacitors normally required to cover the OPERATE/RELEASE times associated with traditional PPS/SPS switchover/failover delays.

Abstract: A power supply failover system/method providing uninterruptable power to protected load devices (PLD) is disclosed. The system includes a failover switch controller (FSC) with inputs from an AC I/V monitor (AIV), AC cycle counter (ACC), failover switch timer (FST), and overcurrent protection timer (OPT). The FSC utilizes these inputs to control failsafe switching of a bypass phase switch (BPS) and AC phase switch (ACS) to the PLD when power from the APS is determined to be good by the AIV. When power from the APS is determined to be compromised by the AIV, the FPS disables the ACS/BPS and enables a DC switch (DCS) and battery isolation switch (BIS) to connect a DC source to the PLD after a time period determined by the FST. APS/DCS overcurrent protection is limited by OPT intervals allowing a smooth transition between the APS to DCS during power failover/failback.
