The boost circuit- It has an inducter, a switch, a diode and a capacitor. A quick change in current through the inducter due to the switch results in a huge voltage across it. This huge voltage creates a huge current which charges up the capacitor. The diode doesn''t let the capacitor discharge, and the voltage keeps building up.
The concept focuses on using voltage boost converters specifically made for electric vehicle (EV) drives to simulate and design switching capacitors.
$begingroup$ @Majenko: The point is to reduce the high frequencies enough so that the active circuit in a voltage regulator can handle the remaining ones. Usually up to a few 10s of kHz is OK. For example, I often use some 950nH 600mOhm 200mA 0805 ferrites. With 22uF capacitance following these, you get one pole at 12 kHz from the R-C action, and another two poles at 35 …
