Steps up a lower input voltage to a higher output voltage.
Steps down a higher input voltage to a lower output voltage. Pulse Width Modulated DC-DC Converters
While the pulse width varies, the frequency typically remains constant, often in the kilohertz (kHz) to megahertz (MHz) range to minimize the size of passive components. Steps up a lower input voltage to a higher output voltage
An LC filter (inductor and capacitor) is used to smooth the pulsed signal into a stable DC output. Primary Converter Topologies the frequency typically remains constant
D=TonT×100%cap D equals the fraction with numerator cap T sub o n end-sub and denominator cap T end-fraction cross 100 %
