電源供應器基本觀念 電源供應器:線性式電源供應器及切換式電源供應器The basic functions of a dc-dc converter are as follows
to provide conversion of a dc input voltage VI to the desired dc output voltage within a
tolerance range
. to regulate the output voltage Vo against variations i
A new equivalent map projection called the parallels plane projection is proposed in this paper. The transverse axis of the parallels plane projection is the expansion of the equator and its vertical axis equals half the length of the central meridia
