This article contrasts power frequency transformers (operating at mains frequencies like 50Hz/60Hz, used in linear supplies) with high-frequency transformers (operating >10kHz, used in switch-mode supplies). Key differences include: HF transformers use ferrite cores for high permeability at high frequencies, enabling efficient transformation of high-frequency pulses and offering ~30% higher conversion efficiency than traditional iron-core LF transformers. Critical selection criteria: match the transformer's frequency rating to the device's requirements to prevent malfunction or damage. Read More »
