The role of electronic transformers in power supply technology

Electronic transformers, along with semiconductor switching devices, semiconductor rectifier devices, and capacitors, are known as the four main components in power supply devices.

1) power transformers that perform voltage and power conversion functions, power transformers, rectifier transformers, inverter transformers, switch transformers, and pulse power transformers 2) Broadband transformers, audio transformers, and mid cycle transformers that transmit broadband, audio frequency, mid cycle power, and signals

3) Pulse transformer that plays a role in transmitting pulses, driving and triggering signals, driving transformer, and triggering transformer 4) An isolation transformer that serves as the primary and secondary insulation isolation, and a shielding transformer that serves as the shielding

5) A phase number transformation transformer that functions as a single phase change three-phase or three-phase to single-phase, and a phase transformation transformer (phase shifter) that changes the output phase A frequency doubling or dividing transformer that changes the output frequency A matching transformer that changes the matching effect between output impedance and load impedance

8) A voltage stabilizing transformer (including a constant voltage transformer) or a current stabilizing transformer that stabilizes the output voltage or current, and a voltage regulating transformer that regulates the output voltage Filter inductor for AC and DC filtering

10) Electromagnetic interference filtering inductor that suppresses electromagnetic interference, and noise filtering inductor that suppresses noise 11) An absorption inductor that absorbs surge current and a buffer inductor that slows down the rate of current change 12) Energy storage inductors for energy storage and commutation inductors for semiconductor switch commutation 13) Magnetic switch inductors and transformers that act as switches 14) Controllable inductors and saturation inductors that regulate inductance

15) Voltage transformers, current transformers, pulse transformers, DC transformers, zero flux transformers, weak current transformers, zero sequence current transformers, Hall current and voltage detectors that transform voltage, current, or pulse detection signals From the above list, it can be seen that whether it is DC power supply, AC power supply, or special power supply, electronic transformers are indispensable. Some people define power sources as DC and AC power sources that undergo high-frequency switching. When introducing the role of soft magnetic electromagnetic components in power supply technology, various electromagnetic components in high-frequency switching power supplies are often cited as examples. At the same time, in the soft magnetic electromagnetic components used in electronic power supplies, various transformers occupy the main position. Therefore, using transformers as representatives of soft magnetic components in electronic power supplies is called "electronic transformers"
