Figure 1: Lab setup of DC microgrid 1. Design of boost converters DC/DC converters play a major part in renewable microgrids. A general circuit of a boost converter is as shown in figure below. The boost converter consists of a high-frequency power switch that charges and discharges the inductor L and capacitor C through two power electronics switches: a controllable switch Q and a diode D. In this model, the diode on-time resistance, the equivalent series resistance of the capacitor, and switch on-time resistance are ignored. The output voltage of the converter is controlled by controlling the duty cycle of high-frequency input pulses; the higher the frequency of the PWM pulses lowers will be the size of the inductor required. The maximum and minimum duty cycle that is required by a boost converter is given by Equations 1 The power electronic switch quickly charges the inductor to high voltages, and then the inductor will in turn charge the capacitor. The inductor can charge the cap
