Its rectifier section employs a three-phase full-bridge thyristor phase-controlled rectifier circuit, while an LC filter assembled from inductors and capacitors is installed on the DC bus to satisfy the operating criteria of the voltage-source inverter.<\/div>\n<div><\/div>\n<div>The voltage-source inverter utilizes a modular parallel layout for scalable power output. Every individual inverter module consists of a single-phase MOSFET full-bridge circuit coupled to a series resonant tank via a high-frequency matching transformer. This matching transformer serves dual purposes: it aggregates output power and optimizes impedance matching, while providing galvanic isolation between the power source and welding load.<\/div>\n<div><\/div>\n<div>A dedicated high-reliability overcurrent protection circuit is integrated to deliver prompt and effective fault response against inverter overcurrent conditions, safeguarding consistent and secure inverter operation.<\/div>\n<div><\/div>\n<div><strong>Advantages:<\/strong><\/div>\n<div>\n<ul>\n<li>\n<div>\n<p><strong>High Temperature &amp; High Withstand Voltage Performance<\/strong><\/p>\n<div><\/div>\n<p>Silicon carbide (SiC) power devices feature a theoretical maximum operating temperature exceeding 600\u00b0C, roughly four times the limit of equivalent silicon (Si) counterparts, alongside a tenfold improvement in blocking voltage rating.
