Title:
POWER SUPPLY FULL-BRICK MODULE WITH INTERNAL INRUSH CURRENT LIMIT CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2023/092313
Kind Code:
A1
Abstract:
A power converter comprises a power conversion circuit and a housing. The power conversion circuit comprises a voltage input, a voltage output, a first DC-DC voltage converter, and a second DC-DC voltage converter coupled to the first DC-DC voltage converter via a converter output bus. A first capacitor terminal is coupled to a first rail of the converter output bus and an inrush circuit coupled to a second rail of the converter output bus and coupled to a second capacitor terminal. The housing comprises a length no greater than 117.3 mm., a width no greater than 61.5 mm., and a height no greater than 14.5 mm. The second capacitor terminal is coupled to the second rail only via the inrush circuit.
