The bipolar pulsed power supply has: a bridge circuit constituted by switching elements SW1 through SW4 connected to positive and negative DC outputs from a DC power supply source; and a control means for controlling switching ON or OFF of each of the switching elements in the bridge circuit. An output-short-circuiting switching element SW0 is disposed between the positive and the negative DC outputs from the DC power supply source such that, in a short-circuited state of the output-short-circuiting switching element, each of the switching elements in the bridge circuit is switched by the control means."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Bipolar pulsed power supply and power supply apparatus having plurality of bipolar pulsed power supplies connected in parallel with each other","description":"A bipolar pulsed power supply which supplies power in a bipolar pulsed mode at a predetermined frequency to a pair of electrodes that come into contact with a plasma is arranged to reduce the switchin","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8506771","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.
