An example apparatus includes multiple AC sources, galvanically isolated from one another, and multiple bridge rectifier circuits, including one or more controllable bridge rectifier circuits, where each bridge rectifier circuit has respective AC-side terminals and DC-side terminals and each bridge rectifier circuit is connected to a corresponding one of the AC sources via its AC-side terminals. The DC-side terminals are connected so that the outputs of the bridge rectifier circuits are combined in series. A control circuit is configured to individually control each controllable bridge rectifier circuit to selectively operate in a regulator mode, whereby a non-zero voltage less than or equal to the maximum rectifier voltage is provided, and a bypass mode, whereby the controllable bridge rectifier circuit provides a negligible voltage to its DC-side terminals and draws negligible current from its corresponding AC source."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Modular thyristor-based rectifier circuits","description":"Power conversion apparatus for controllably converting alternating current (AC) to direct current (DC).
