Inverters are vital components of aircraft electrical systems, but they are not immune to issues. Recognizing and addressing common inverter problems is essential for ensuring aircraft safety, reliability, and passenger comfort. Implementing solutions such as improved cooling, voltage regulation, and redundancy can help mitigate these challenges.

In this paper, dual-input-dual-output (DIDO) dc-dc converter is used to interface solar PV and battery sources for CubeSat Electrical Power System. This non-isolated converter topology is efficient, compact and has fewer circuit components with only one inductor. DIDO topology is suitable for 3U to 6U CubeSat. Further, the proposed converter ensures MPPT operation of PV source using Fuzzy Logic Controller. Detailed Electrical Power System design and analysis for CubeSat presented.
