Strong pulse characteristics of the new phased array radar pose severe challenges to the stable and reliable operation of airborne power supply systems. Limited by strict volume and weight constraints

large-capacity passive capacitors cannot be adopted in airborne power supply systems for pulse power decoupling. To solve this problem

a rectifier with dual DC output ports including a pulse decoupling port and a constant-voltage DC port was designed. Pulsed loads were separated from conventional loads to prevent transient impacts of pulsed loads from interfering with the normal operation of conventional loads. Meanwhile

wide-range voltage fluctuation was permitted at the pulse decoupling port

which achieves pulsed energy smoothing and greatly reduces the capacitance required for decoupling. The topological structure and operating principle of the dual-DC-port rectifier were analyzed in detail. A switched SVPWM strategy and the corresponding system control method catering to power port regulation requirements were proposed and investigated. The suppression of pulsed power fluctuations and accurate power distribution between the two ports were realized. Finally

a prototype was built

and effectiveness of the proposed dual-DC-port rectifier in pulse power decoupling is verified by experimental tests.
