The control voltage generator circuit comprises a top-up circuit (10) for maintaining the voltage VCin on an input capacitor (12) at least at supply voltage VS, and a bidirectional DC-DC converter circuit (20) having a variable voltage conversion factor G controlled by control input signal (27). The bidirectional DC-DC converter (20) is arranged to convert voltage, at the voltage conversion factor G, between the input capacitor voltage VCin and the output voltage VC. When VC<G×VCin, the DC-DC converter circuit (20) uses charge stored in the input capacitor (12) to charge the capacitive load (1). When VC>G×VCin, the DC-DC converter circuit (20) uses charge stored in the load capacitance (1) to charge the input capacitor (12)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Variable voltage generator circuit, capacitor and method","description":"A variable voltage generator circuit is described for generating, from a substantially constant supply voltage VS, a variable high-voltage control voltage VC for a variable power capacitor (1) having ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11496059","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
