Different from the compensation with error amplifier in voltage mode and current mode, the zero formed by output capacitor ESR is used for loop compensation in the original D-CAP control [3 and 4].
capacitor and analyzes the loop stability. D-CAP2TM and D-CAP3TM converters achieve low ESR ceramic output capacitors through ripple injection circuit. But many designers still prefer to use an electrolytic capacitor or polymer to obtain high capacitance for better ripple and transient performance.
In D-CAP2 and D-CAP3 schemes, the limitation on the use of small ESR capacitor is broken through with the internal ripple injection circuit. The frequency loop models of D-CAP and D-CAP2 control schemes have been studied in some previous application reports.
The experiment discussed in this or capacitor packages in series. One was connected to a DC block. The voltage across the two series capacitors will be for small signal analysis. A PCB was designed to characterize from 0 V to 800 V. An environmental chamber was used to 25 C–150 C). A network analyzer was used to inject a small connected capacitors.
Regarding the selection of the capacitance value of DC-bus capacitors, on the one hand, the rated current that the capacitor passes through should be greater than the current ripple it bears, and on the other hand, it can withstand voltage ripple below 10% of the rated voltage. ... ...
