Each of the d parallel connected three phase DC power supply comprises a boost power factor corrector to convert an AC power source to a rectified and filtered DC voltage, an isolation transformer connected to the boost power factor corrector to generate a full wave rectified DC voltage having stable voltage level, a duck switching circuit consisting a first, a second and a third semiconductor switches to regulate the voltage level of the output of said isolation transformer and a phase controller to manage an interleaved phase of the output of said three semiconductor switches. The multiphase DC power supply uses interleaved power factor correction technology to successfully provide a DC power supply with high switching frequency, low ripple noise and not subject to EMI."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multiphase DC power supply with high switching frequency","description":"A multiphase DC power supply with high switching frequency of 1 MHz comprising three parallel connected three phase DC power supply.
