WebFeb 23, 2024 · Yes, any DC current into the transformer can cause the core to saturate. It's the average value of the waveform that determines its DC content. Thus a unipolar signal has an average DC value, so cann0t be applied to a transformer. To block any DC, you can use a large series capacitor which will pass the AC but not the DC. WebAug 16, 2024 · Transformers do not work on DC supply. Let us see why. The transformer works on the principle of mutual inductance i.e. current in one winding must change uniformly to induce the EMF in the other. When a DC voltage V is applied to the primary of a transformer, the primary will draw a constant current or direct current and hence, the …
