Electronic transformer and semiconductor switching devices, semiconductor rectifier devices, capacitors together, known as the power supply device in the four main components. Today, let Xiaobian take you to know what types of electronic transformers are divided into. Let's take a look together.
According to their role in the power supply device, electronic transformers can be divided into:
The power supply transformer, power transformer, rectifier transformer, inverter transformer, switching transformer, pulse power transformer;
Broadband transformer, audio frequency transformer, mid-cycle transformer, which plays the role of transmitting broadband, audio frequency, mid-cycle power and signal;
Pulse transformer, driving transformer, triggering transformer, which plays the role of transmitting pulse, driving and triggering signal;
An isolation transformer playing the role of insulation isolation of the original side and the secondary side, and a shielding transformer playing the role of shielding;
A phase number conversion transformer playing the role of single phase to three phase or three phase transformation phase, a phase conversion transformer playing the role of changing the output phase (phase shifter); 6) Frequency doubling or frequency division transformer to change the output frequency;
A matching transformer to match the output impedance with the load impedance;
A stable voltage transformer (including a constant voltage transformer) or a stable current transformer, a voltage regulating transformer to regulate the output voltage;
Filter inductors acting as AC and DC filters;
Electromagnetic interference filter inductor to suppress electromagnetic interference, noise filter inductor to suppress noise;
An absorbing inductor to absorb the surge current and a buffer inductor to slow down the rate of current change;
The energy storage inductor plays the role of energy storage, the commutator plays the role of helping the semiconductor switch commutator;
Magnetic switching inductors and transformers acting as switches;
A controllable inductor and a saturated inductor acting as an inductor regulator;
