The working principle of high-frequency transformers is based on the principle of electromagnetic induction. High-frequency transformers have two sets of coils. Primary and secondary coils. The secondary coil is outside the primary coil. When alternating current is applied to the primary coil, the high-frequency transformer core generates an alternating magnetic field, and the secondary coil generates an induced electromotive force. The turns ratio of the high-frequency transformer coil is equal to the voltage ratio. For example, the primary winding is 500 turns, the secondary winding is 250 turns, the primary winding passes 220 volts alternating current, the secondary voltage is 110 volts, and the high-frequency transformer can be stepped or boosted. If the number of turns of the primary coil is less than the number of turns of the secondary coil, that is, the voltage increase belongs to the step-up transformer, and the low voltage can be increased to the high voltage.
