Linear DC/DC Conversion
Passive Linear Conversion
Passive conversion means that there are no control components involved in the process that are
capable of changing the conversion properties in any way; i.e. the steady state input-to-output transfer
function is not adjustable in runtime. The consequence of this is Load dependent output voltage.
Active Linear Conversion
By “active” conversion we mean that there are components involved that are capable of influencing
the conversion activity; i.e. there is at least one semiconductor capable of controlling the conversion
by at least one additional input signal. This might be to stabilize the output to a reference level for
example.
