Abstract
PURPOSE: To accurately predict the characteristics of a magnetic core with a simple configuration by contracting the characteristics of a semiconductor rectifier equivalently using a voltage follower circuit employing an operational amplifier, combining the characteristics with the magnetic core to form a similar circuit to the actual case.
CONSTITUTION: The forward voltage drop of a rectifier Dd in a rectifying circuit is applied to the non-inverting input terminal of an operational amplifier OP. Thus, the output of the amplifier OP is applied to a non-inverting inout terminal. When the amplifier OP oprates as a voltage follower and the output from the amplifier OP is applied to a resistor R, the voltage drop between the terminals P and N becomes zero. Output windings NL' are wound on two magnetic cores Cr1, Cr2, and are energized by AC power supplies Ea1', Ea2' through a rectifier Di and a load resistor RL'. The control windings Nc' are connected in series with each other, and the control currents ic' are supplied through the resistor Rc' to the windings Nc'. Shorting windings Ns' are shorted through a resistor Rs'. The time constants of the respective units are determined to the actual application. Thus, the characteristics of the magnetic cores applied to actual case can be accurately predicted with a simple configuration.
