Reliability improvement of power inverters through environmental stress simulation

A cost-effective method of qualifying and improving the reliability of adapted designs through the evaluation of design performance under simulated military environmental stresses is demonstrated. The example discussed is the implementation of an Avionics Instrument Incorporated AI² static inverter as part of the Traffic Jam electronic countermeasures system. In the case of the AI² static inverter employed in the AN/TLQ-17A(V)3 system, the iterative process of test and design modification has allowed the procurement of systems with the required functionality and reliability at minimum cost to the government
