Abstract : This paper focuses on 150KW induction furnace employed with a reconfigured Series Resonant Converter (SRC) under faulty conditions. Resonant converter topologies have been popular for a few years in high-power transmission viz. medical, biotechnology, nuclear fusion. This network design is frequently utilized in solid-state transducers, where fault tolerance is an important feature that may be achieved through redundancy. Fault tolerance is an important element of power applications since it makes the system more reliable and available. A critical feature of any fault tolerance topology is the early detection of faults and their rectification or prevention. There are a variety of fault-tolerant topologies available in industry; however most of them rely on redundancy, which raises the cost and maintenance work. In an application with little or minimal redundancy, there is still room for improvement in terms of failure tolerance. The goal of the suggested topology is to increase efficiency while decreasing redundancy. It is frequently designed to accomplish converter fault tolerance by resetting the network during each failure, which may weaken the converter's performance but stops it from working. For example, induction furnaces are frequently used in a variety of industrial processes, including waste energy generation, metal melting, welding, and hardening. because fault-resistant topologies and high power under all circumstances are necessary for these jobs. Reconfiguration of the circuit under faulty conditions is examined in this project, so that a full bridge under faulty conditions is reconfigured as a half bridge for specialized applications such as an induction furnace, etc.
