Boost converters boost the input voltage higher
Circuit Diagram Edit
Boundary between dis and cts ConductionEdit
Discontinuous conduction mode is the preferred method of operation for a buck-boost converter.
note & average current through inductor equates to the current through the inductor minus that which flows back to the source. The capacitor has zero average current.
Output Voltage Ripple Edit
The diode current carries both the ripple current from capacitor and the average current through the load. Hence
