Patent number: 9537351Abstract: 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.Type: GrantFiled: October 30, 2015Date of Patent: January 3, 2017Assignee: LITE-ON, INC.Inventors: Victor K.
