Analysis of Multi-Input Multilevel Boost Inverter Circuit with Optimal Firing Angles Using dSPACE
Tóm tắt
The DC load utilities are increased due to the modern development of alternate renewable Energy sources and Electric Vehicles. Contemporary applications like Electric Vehicles require multiple voltages that require separate DC-DC converters. Usage of more power electronic converters for multiple loads leads to more harmonics and high switching loss. To minimize the losses and improve efficiency, this paper presents a new multilevel inverter topology with multiple outputs and multiple inputs. This circuit combines a multi-input multistage DC-DC converter for various DC voltage levels and a level shifter circuit with H-Bridge. The performance of the circuit was analysed using Phase opposition and disposition modulation and optimal firing angle PWM techniques. Pulses for DC-DC converter and multilevel inverter are generated using MATLAB/Simulink environment and integrated with hardware prototype using dSPACE- ds1104 interface.
