Description

Suitable for the adjustable single-phase optocoupler times flow pattern buck rectifier of high companding flow structure
Technical field
The utility model is related to a times flow pattern rectifier, more specifically, is a kind of be related to suitable for high companding flow structure Adjustable single-phase optocoupler times flow pattern buck rectifier.
Background technology
Currently, it is used in traditional current doubler rectifier in high-frequency rectification field more, compared with full-wave rectifying circuit, times stream rectification The vice-side winding of the high frequency transformer of device only needs a single winding, without centre cap；Compared with full bridge rectifier, times stream The few half of number of diodes that rectification circuit is used.Therefore, current-doubling rectifier combines full-wave rectifying circuit and full-bridge rectification The advantage of both circuits.Certainly, current-doubling rectifier will be more using an output inductor, structure slightly complicated.But this electricity The working frequency and conveying electric current of sense are the half of inductance used in full-wave rectifying circuit, therefore can be made smaller, also beneficial to scattered Heat, additionally it is possible to reduce and improve the ripple of output voltage.But there is also person, some problems need into one traditional current doubler rectifier Step is solved：
（1）Traditional current doubler rectifier is not directly applicable high-pressure type rectification circuit, to realize that step-down rectifier is exported, leads to Often to be matched therewith in its input increase step-down transformer, thus can produce higher cost；
（2）Traditional current doubler rectifier is suitable only for high-frequency rectification circuit, its ac input end need to provide symmetrical high frequency just, Negative square wave power, is generally unsuitable for the ac input end power supply of the other forms such as sine wave, triangular wave, sawtooth waveforms；
（3）The device used inside traditional current doubler rectifier is difficult to expand output current once solidifying, and is not easy to straight Connect realization and expand output power of power supply；
