A control circuit can be configured to sample the input voltage (VIN) and then generate a pulse with a duration inversely proportional to VIN so as to control the boost converter switches such that a substantially constant peak inductor current is generated.CALHOUN Benton H....
Boost converter input ripple current reduction circuit A boost inductor value reduction circuit is integrated into a traditional boost power converter to greatly reduce undesirable high frequency harmonics from being fed back to the input side of the boost power converter.

In summary, the boost converter uses the inductor as a source, along with the supply voltage, to boost the output voltage. The output reservoir capacitor receives a flow of charge through the inductor each time the switch opens. If the load does not draw sufficient current, the regulator ...
This paper describes the soft switching dc-dc converter with the coupling inductor for continuous current mode operation. The coupling inductor makes the commutation of the auxiliary inductor current at switching off to realize the zero current switching at switching on. The coupling inductor also make...
The total of the inductor current I L and the capacitor discharge current I 2 is the load current I O. Tips The buck converter is a forward converter that sends energy to the load when the power switch is turned on. Figure 2-1 depicts the voltage and current waveforms of a step-down...
A boost converter is a DC/DC power converter which steps up voltage from its input (source) to its output (load). In continuous conduction mode (current through the inductor never falls to zero), the theoretical transfer function of the boost converter is: ...
