Saturable Cores

Product Briefs

The Magnetic amplifier, or Mag-Amp, method of secondary regulation in switching power supplies can lead to benefits such as miniaturization, high efficiency, low noise, high reliability, and high precision. A Mag-Amp consists of a saturable reactor (a wire-wrapped saturable core). With the introduction of amorphous saturable cores, Mag-Amp have became more practical and so their use has become more wide-spread. The Mag-Amp method is the most suitable voltage regulation method for the switching power supply in personal computer. The "MS" series of amorphous saturable cores provides the stable magnetic performance required by Mag-Amp at an excellent price. This makes the "MS" series an ideal choice for designers of PC power supplies.
