| 摘要 | A post secondary magnetic amplifier circuit for operation at frequencies at or above 100 kHz with minimal losses is described. A magnetic amplifier is used to control the post-secondary current to an LC filter in which the magnetic amplifier is constructed using an non-nickel core material such as ferrite having a very narrow B-H operating curve (flat loop) in which the remanence (residual magnetism) is below 1000 gauss. The magnetic amplifier then operates as a controlled inductance so that saturation is approached slowly. | ||||||
