Analysis, Control and Simulation of Switched Boost Network Inverter using Modified PWM approach for E-bike Applications

A transformer less with modified PWM approach control switched boost network inverter to supply the motor in the E-bike application is demonstrated in this work. The output received from battery is of low magnitude DC voltage, making it unsuitable for high power AC applications. Traditionally, to make the low power DC obtained suitable for high power AC applications, integration of boost chopper and conventional VSI is used, resulting in two stage conversion, making the overall system bulkier and more expensive, and unsuitable for low power consumptions. To address this issue, Z-source inverter (ZSI) can be used, but ZSI uses two LC pairs in its front stage, making the system bulkier. This paper presents a switched boost network inverter (SBNI) topology with features alike ZSI albeit without the detriment of a high component count and involves controlled shoot through operation without harming converters functionality. The steady state and small signal analysis of the proposed topology, as well as the proposed PWM strategy, are discussed. In the MATLAB/SIMULINK environment, the topology and proposed PWM technique are validated. The obtained results show a good significant relation between the theoretical and simulated waveforms.
