MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611100496 A) filed by Madan Mohan Malaviya University Of Technology on August 19, 2026, for A Reduced-Switch Three-Phase To Single-Phase Multilevel Cycloconverter System.
Inventors include Navdeep Singh; and Mukhraj Yadav.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A reduced-switch three-phase to single-phase multilevel cycloconverter system (100) and method provide direct AC-to-AC power conversion with high-frequency galvanic isolation. The system (100) incorporates a Scott-connected transformer arrangement (101) that converts a three-phase AC input into two isolated, balanced single-phase outputs (V_1, V_2) displaced by 90°. The system (100) features a reduced topology comprising twelve power semiconductor switches (S_1–S_12) and twenty-four power diodes (D_1–D_14). Optically isolated gate driver circuits (102) deliver synchronized pulse-width modulation (PWM) signals to control the switches across eight operational modes, synthesizing a high-frequency pulse train into a low-frequency multilevel single-phase AC output voltage with reduced total harmonic distortion (THD). The arrangement provides uniform input phase balancing, reduced component count, lower switching losses, and variable output frequency control.
