The input rectifier circuit includes a passive half-bridge rectifier circuit functional to provide passive rectification of an AC input power sign and at least one current shaper circuit. The current shaper circuit includes an input inductor coupled between the AC input and a switch node in the input active rectifier circuit. The input current shaper circuit is functional to shape an AC input current signal associated with an AC input power signal to a substantially sinusoidal current signal. A bulk capacitor circuit is coupled to the input active rectifier circuit. A DC/AC converter circuit is coupled to the bulk capacitor circuit. A resonant circuit is coupled to the DC/AC converter circuit and an output rectifier circuit may be coupled between the resonant circuit and the DC output."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"AC/DC power converter with active rectification and input current shaping","description":"An AC/DC power converter has an AC input and a DC output, with an input rectifier circuit coupled to the AC input.
