Magamp method

A method that controls the output by using a saturable core on the secondary side of the transformer in the power supply circuit. It utilizes the characteristic that the core has high impedance and remains in the off state before saturation, and low impedance and switches to the on state after saturation, to control the output. By changing the bias, the output is controlled by varying the duration of the on and off states. The mag amp method offers high cost-effectiveness when the voltage is low and the current is high. Therefore, it is commonly used in power supplies for desktop computers, servers, copiers, printers, and mobile phone base stations.
