High-frequency transformers operate above 10kHz for switching/inverter power applications, requiring minimized leakage inductance and distributed capacitance to prevent power losses during high-frequency pulse transmission. Pulse transformers function as wide-band devices for radar/impedance matching applications, utilizing core saturation to convert sine waves into narrow pulses while prioritizing nonlinear distortion control and loss reduction in communication scenarios. These distinct operational principles define their fundamental differences. Read More »
