Patent number: 10998820Abstract: An illustrative embodiment described herein is a stacked direct current to direct current (DC-DC) converter including a first DC bus coupled to a first one of a power source and a power load and a second DC bus coupled to a second one of the power source and the power load. The stacked DC-DC converter includes a first half-bridge coupled to a first portion the first DC bus and a second half-bridge circuit coupled to a second portion the DC first bus. The stacked DC-DC converter includes a third half-bridge circuit coupled to a first portion of the second DC bus and a fourth half-bridge circuit coupled to a second portion of the second DC bus. The stacked DC-DC converter includes a first magnetic element coupling the first half-bridge circuit to the third half-bridge circuit and a second magnetic element coupling the second half-bridge circuit to the fourth half-bridge circuit.Type: GrantFiled: August 22, 2019Date of Patent: May 4, 2021Assignee: EPC Power CorporationInventor: Devin Dilley

Patent number: 10892682Abstract: An electrical power conversion system includes an alternating current (AC)-to-direct current (DC) power converter that is configured to convert power between AC power and DC power. The AC-to-DC power converter includes switching legs that each connect to a phase of the AC power. Each of the switching legs includes two electronic devices connected in series with one another between a positive DC bus terminal and a negative DC bus terminal. The electrical power conversion system also includes a DC-to-DC power converter that is configured to convert power between the DC bus power and DC terminal power via a positive DC terminal and a negative DC terminal. The DC-to-DC power converter is configured to control a differential voltage between the positive and negative DC terminals and a common-mode voltage that is between a neutral of the AC power and each of the positive and negative DC terminals.Type: GrantFiled: June 1, 2018Date of Patent: January 12, 2021Assignee: EPC Power CorporationInventors: Devin Dilley, Ryan Smith

Patent number: 10153707Abstract: A configurable power converter includes an interchangeable face plate mounted to a chassis and circuit terminals mounted to the face plate. Each of the circuit terminals are configurable as input or output circuit terminals. The power converter also includes a direct current bus within the chassis that includes a positive terminal and a negative terminal. The power converter also includes electrical switches connected between the positive and negative terminals. The power converter further includes a controller that operates the electrical switches to provide electrical power to the direct current bus from power received from the input circuit terminals and operates the electrical switches to provide power to the output circuit terminals from power of the direct current bus. The input and output circuit terminals can each support alternating current power or direct current power.Type: GrantFiled: April 8, 2016Date of Patent: December 11, 2018Assignee: EPC POWER CORPORATIONInventors: Devin Dilley, Ryan S Smith

Publication number: 20140001344Abstract: A night vision device with a switching power supply and a method of powering a night vision device with switching circuits are provided. The switching power supply converts a battery voltage to high DC voltages for powering photocathode, screen, and MCP of the night vision device. The switching power supply generates and adjusts a photocathode voltage instruction signal having a duty cycle based on the difference between a reference photocathode voltage and the output voltage of the photocathode voltage circuit. The switching power supply generates and adjusts a screen voltage instruction signal having a duty cycle based on the difference between a reference screen voltage and the output voltage of the screen voltage circuit. The switching power supply performs the automatic brightness control and auto-gating without directly sensing the output load current.Type: ApplicationFiled: July 2, 2012Publication date: January 2, 2014Applicant: EPC PowerInventor: Todd L.
