A comprehensive study and analysis of second order harmonic ripple in DC microgrid feeding single phase PWM inverter loads

The paper presents a detailed analysis of second order harmonic ripple in a DC microgrid. A boost converter feeding PWM inverter load is considered and equivalent circuit is proposed. The effect of the size of input capacitor, output capacitor and inductor of boost converter, on this ripple has been investigated. The proposed model has been validated through experimentation and simulation.
