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. |

| PURPOSE:To maximize or minimize rapidly the output of a magnetic amplifier by applying a DC voltage across output winding when a command current is zero. CONSTITUTION:For gate control over chopper CH, magnetic phase shifter MPS is used to control the turning direction of electric motor M. With forward/backward lever FRL switched, the output of oscillation stop circuit 4 turns transistor Tr4 ON and Tr3 OFF, eliminating command current Ic1. Simultaneously, a base current flows to Tr1 and Tr2, series-connected to output windings NL1 and NL2 of phase shifter MPS, by way of diode D7 and resistance r7, and diode D8 and resistance r8 respectively. Therefore, Tr1 and Tr2 conduct with Tr4 ON and DC voltage Vcc are applied across windings ML1 and NL2. As a result, the output phase-shift width of phase shifter MPS is maximized and the response time for maximizing the output phase shift width can greatly be shortened. Additionally, this can similarly be applied to a magnetic amplifier which is not used as a phase shifter. | ||||||

| A magnetic amplifier includes a saturable core having a plurality of legs. Control windings wound around separate legs are spaced apart from each other and connected in series in an anti-symmetric relation. The control windings are configured in such a way that a biasing magnetic flux arising from a control current flowing through one of the plurality of control windings is substantially equal to the biasing magnetic flux flowing into a second of the plurality of control windings. The flow of the control current through each of the plurality of control windings changes the reactance of the saturable core reactor by driving those portions of the saturable core that convey the biasing magnetic flux in the saturable core into saturation. The phasing of the control winding limits a voltage induced in the plurality of control windings caused by a magnetic flux passing around a portion of the saturable core. | ||||||

| A magnetic amplifier includes a permeable core having multiple legs. Control windings wound around separate legs are spaced apart and connected in series in an anti-symmetric relation. Harmonic filters are positioned adjacent to the control windings to attenuate even-ordered harmonics generated by alternating load current passing through a portion of the legs. The control windings bias magnetic flux arising from control current flowing through one of the control windings which is substantially equal to the biasing magnetic flux flowing into a second control winding. The flow of the control current through each of the control windings changes the reactance of the permeable core reactor by driving those portions of the permeable core that convey the biasing magnetic flux into saturation. The phasing of the control winding limits a voltage induced in the plurality of control windings caused by a magnetic flux passing around a portion of the permeable core. | ||||||

| A circuit for combining first and second signals having the same frequency. The signals have a relative phase shift, 2a(t). The circuit generates a signal that is proportional to the sum or difference of signals. The circuit appears to be a resistive load; however, the circuit can be constructed from purely reactive circuit elements, and hence, does not dissipate energy. In one embodiment, the circuit is constructed from a transformer and two LC circuits in which the capacitance is varied in response to a(t). The circuit may be used to construct a high efficiency RF amplification stage. | ||||||
