Phase-shifted full-bridge transformer

Description

The phase-shifted full-bridge transformer uses a full-bridge converter composed of two sets of four-quadrant power switches to perform high-frequency modulation and demodulation of the input power frequency voltage.，And use high-frequency transformers to achieve electrical isolation。Use phase shift control to adjust the amplitude of the output power frequency voltage，Achieve continuous regulation of output voltage，Realize closed-loop control of system output。This not only replaces the function of a traditional transformer，and expanded its functionality。

Advantages：

(1)Leakage inductance can be controlled within 1%-10% of the main inductance；High leakage inductance accuracy；

(2)The magnetic core has good electromagnetic coupling，Simple structure，High production efficiency；

(3)High working frequency，High power density，Frequency is around 50kHz~300kHz。

(4)Excellent heat dissipation characteristics，Has a high surface area to volume ratio，Hot aisle is short，Easy to dissipate heat。

(5)High efficiency，The special geometric shape of the magnetic core structure can effectively reduce core losses.。
