Realization of HMC Based Indigenous High Current Solid State Switch Controller for Aerospace Applications

The development of Solid-State Switch with a high current rating in hybrid compact package, poses significant challenges in fabrication, testing and qualification for space applications. These challenges have been effectively addressed by incorporating advanced packaging materials, bonding materials, and improving thermal management through optimal layout design techniques. The paper focuses on articulating the advantages of Solid-State Switches over electro-mechanical switches, detailing the design approach and outlining fabrication and qualification processes. The successful development of the Solid-State Switch is a testament to the excellence of HMC endeavour, meeting all requirements to operate satisfactorily in harsh conditions of space.
