TRANSFORMER SIMULATING CIRCUIT AND SIMULATING METHOD OF TRANSFORMER

A transformer simulating circuit includes a primary side, a secondary side, a first coupling capacitor, and a second coupling capacitor. The primary side includes a primary core-loss resistor, a primary intra-winding capacitor, and a magnetizing inductor connected in parallel, and includes a primary leakage inductor module connected between a primary winding and the primary intra-winding capacitor, and a primary winding resistor connected to the primary leakage inductor module. The secondary side includes a secondary leakage inductor module connected between a secondary winding and a secondary intra-winding capacitor, and a secondary winding resistor connected to the secondary leakage inductor module. The first coupling capacitor and the second coupling capacitor are connected between the primary side and the secondary side. Therefore, a simulated frequency response of the transformer simulating circuit is closer to a measured frequency response of a real transformer.
