A Twenty Five Switch Inverter Topology for Controlling Two Independent Five-Phase Load

The inverter drives for controlling multiple loads will provide several advantages like lower power electronic components, costs, space, etc. In this paper, a new Three-Level (3L) Neutral Point Clamped (NPC) inverter topology for controlling the two independent Five-Phase Load (FPL) is proposed which is named as Twenty Five Switch Inverter (TFSI) topology. This TFSI topology has five switches and two diodes in each leg. The number of switches in the conventional two load inverter is 30 switches which is reduced to 25 switches in the proposed topology. The Space Vector Modulation (SVM) for the proposed TFSI topology has 1024 vectors which is the addition of two individual Five-Phase Three-Level (FPTL) SVM. The performance of two loads for the proposed topology is examined at different conditions like changing the fundamental frequency (f
_o
), switching frequency (f
_sw
) and modulation indices. The simulation is carried out with MATLAB/Simulink and the results are validated with hardware implementation.
