In contrast, the single inductor in an inverting buck-boost converter has an average current of IIN + IOUT. The coupling capacitor sees significant root-mean-square (RMS) current relative to both input current and output current, which generates extra power loss and reduces the converter''s overall efficiency.

A buck-boost converter is typically made up of a switch, an inductor, a diode, and a capacitor. The switch controls the conversion mode, toggling between buck and boost operation. When the switch is on, the inductor stores energy, and when the switch is off, the inductor releases energy to the load through the diode.
Capacity [C]: capacitor capacity expressed in μF (microfarad). Nominal voltage of the capacitor [V]: the connection, in series, of capacitor and reactor causes an increase in voltage at the capacitor terminals due to the Ferranti Effect that must be considered in
Shunt Capacitors are switched on when kVA demands reactive power increase and voltage of the receiving end is reduced. The switching of the shunt capacitor compensator increases the voltage at the receiving end. Thus it improves the power factor and voltage
This application note provides basic formulas that you need to design the power stage of an inverting buck-boost converter. The premise is that the power switch is integrated in the IC and the rectification is done by a diode (non-synchronous power stage).
buck-boost converter has high switch voltage stress (V in +V o), therefore it is also not the popular one. The boost converter has the filter inductor on the input side, which provides a …
