Low-noise multi-output power supply circuit featuring efficient linear regulators and method of design |
摘要 |
<p>A low noise, multiple output power supply circuit featuring a plurality of efficient linear regulators (18) comprises a transformer (12) having a primary circuit (6) with a primary transformer input winding (N1) and a plurality of secondary circuits (8). Each secondary circuit has a secondary transformer output winding (N2-N6) having the same number of turns of secondary windings. A saturable reactor core (Lsat) is placed in series with at least one selected output winding of at least one selected secondary circuit to subtract a small amount of average voltage, volt-seconds, from the output voltage of the selected output winding to allow different rectified DC voltages to be obtained from different output windings which have the same number of turns. <IMAGE></p> |
