Figure 1. Functional block diagram of a buck converter operated in ACMC. In the diagram, CEA = current-error amplifier, CSA = current-sense amplifier, VEA = voltage-error amplifier. The inductor current signal, iL, is discussed below and in Figure 2. To better understand ACMC...
where Vref_droop is the value of the Output voltage reference demand parameter. If you set the Voltage reference parameter to External, the block uses the constant value of the Voltage reference used to calculate droop percent parameter to calculate the droop instead. This plot shows how the blo...
the power balance management can be considered as theDC bus voltageadjustment. To ensure normal operation of the DCmicrogrid, the value of the DC bus voltage must be kept within a reasonable range[113]. In a DC microgrid,there are two main selections for the DC bus voltage base value: ...
DCR is the DC equivalent resistance of an inductor L. ESR is the equivalent series resistance of an output capacitor. Thus, the LC filter transfer function is Obviously, the ESR would generate a zero for a control loop. When the ESR is too large to ignore, the designer should consi...

The capacitance is used to block the DC power dissipation, and the ESR is used to damp filter output impedance in mid-frequency. For some solution size sensitive or height limited applications, an electrolytic capacitor might be too large to be assembled on the PCB board. A ceramic capacitor ...

Step-down converter operation Figure 1 shows the basic block diagram for the power stage of the TPS62090 low-power synchronous step-down converter. The switch pins (SW) connect to the output filter (inductor and capacitor), which generates the regu- lated output voltage. When the high-side ...
(dotted line) feeds the output voltage back to the switching block; this changes the switching operation to compensate for output voltage deviations from the desired value regardless of whether they are caused by changes in the input voltage (for example, a supply battery slowly being drained) ...
The general principle of operation of the primary switched-mode regulator is shown in the block diagram of the single-ended forward converter: The non-stabilized supply voltage is first rectified and filtered. The capacitance of the capacitor in the DC link determines the hold time of the power...
