The Transformer Rectifier Unit (TRU) in aircraft is DC power supplies. Three-phase AC power supplies are available as long as they work. DC power distribution, on the other hand, provides DC power directly to all DC users, providing input power to the emergency AC distribution system so that the static inverter can generate AC power. To the voltages produced by TRUs to be less oscillating and of higher quality, multi-pulse ones are studied and recommended for aircraft systems. In this study, Zener diode filtered multi-pulse rectifier, which can further reduce the oscillations in the output voltage, is recommended for aircraft. Three-phase half-wave rectifier design and analysis are presented to better demonstrate the effectiveness of Zener diode regulation in multi-pulse TRUs. First, the parts of the power system, which includes the rectifier circuit of a two-engine aircraft and fed by this rectifier, are given. The circuit structure and working order of the rectifier are given with mathematical explanations. In the application phase, low oscillating output voltages and currents are obtained by creating currents and voltages on the load for different Zener voltages. Conventional rectifiers and the proposed rectifier are tested on the same loads, and comparisons are done.
