Modeling and Simulation of Current Ripple in DC Link Connecting Two PWM Inverters Using Matlab/Simulink

In this paper, the impacts of PWM carrier signals to DC bus current ripple in a PWM-based generator-load system will be investigated. The study is crucial to aid in the determination of the dc bus capacitor in a real-world inverter system. A Simulink model depicting the contribution of the generator current and the load current to the total DC bus current will be described. Results of the computer simulations will also be discussed.
