Web2.1 Voltage regulation The solid line in Fig. 2a shows the effect of the variations of the droop gains on the voltage regulation in the DC-MG under study. As shown in this figure, increasing the droop gains results in voltage regulation deterioration, thus, the voltage regulation may not be desirable, especially for heavy load conditions. WebWith VIN = 10 V, the modulator voltage gain Km = 10. The linear model for the current loop is an amplifier which feeds back the dc value of the inductor current, creating a voltage-controlled current source. This is what makes the inductor disappear at dc and low frequency. The ac ripple current sets the modulator gain.
