Description

双级升压高频电源拓扑、臭氧发生装置及洗衣机集成电路
技术领域
本发明属于高频电源技术领域，尤其涉及一种双级升压高频电源拓扑结构、臭氧发生装置集成电路及洗衣机集成电路。
背景技术
臭氧发生器是用于制取臭氧气体(O3)的装置。臭氧易于分解无法储存，需现场制取现场使用(特殊的情况下可进行短时间的储存)，所以凡是能用到臭氧的场所均需使用臭氧发生器。臭氧发生器在饮用水，污水，工业氧化，食品加工和保鲜，医药合成，空间灭菌等领域广泛应用。臭氧发生器的分类按臭氧产生的方式划分，主要有三种：一是高压放电式，二是紫外线照射式，三是电解式。
利用电离反应产生臭氧实现杀菌除臭的装置往往需要高压电源，而以往使用的电源一般是前级推挽式升压，后级 BOOST升压、前级BOOST升压，后级推挽式升压或桥式升压，但是往往电路结构较为复杂，且噪音较大。
发明内容
为解决上述的技术问题，本发明提供了一种新的双级升压高频电源拓扑结构，集成于洗衣机或干衣机的臭氧发生装置，实现双级升压高频电源体积小型化、降低功耗并实现高频无噪音。
为实现上述目的，一方面，本发明公开了一种双级升压高频电源拓扑结构，包括：
一直流滤波电路，电性连接输入电源，用于将所述输入电源输入的直流电稳压、滤波后输出，设输出电压为Vs；

一BOOST升压电路，电性连接所述直流滤波电路及自激推挽式变换器；
所述BOOST升压电路与所述自激推挽式变换器组合升压、互补协作，以输出高频高压电源。
进一步地，双级升压高频电源拓扑结构还包括一反馈电路，电性连接所述高频变压器、BOOST升压电路及一控制单元，用于检测高频变压器的输出电压值进行反馈控制。

一第二开关管Q2，第二开关管Q2的栅极经一电阻R4 连接高电平VD1，第二开关管Q2的漏极连接高频变压器T1 的引脚12。
进一步地，所述直流滤波电路还包括：
一电感L5，电性连接所述输入电源；
一共模电感L1，电性连接所述电感L5；及
一电容C1，并联连接所述共模电感L1。
进一步地，所述BOOST升压电路还包括：
一二极管D4，输出端电性连接所述直流滤波电路输出端及所述高频变压器T1输入端；
一电感L2，电性连接所述二极管D4的输入端及所述自激推挽电路；及
一开关电源模块U4，电性连接所述二极管D4和电感L2的输入端；
其中，所述开关电源模块U4作为电感L2的电源，开关电源模块U4开通时为电感L2充电，当开关电源模块U4关断时，电感L2放电，使二极管D4导通，电感L2经二极管 D4输出电压VL2至所述高频变压器T1的引脚13，因此，高频变压器T1的初级电压为Vs+VL2。
进一步地，所述反馈电路进一步包括：
一第一开关控制模块U1，电性连接所述高频变压器T1 的输出端；
一第二开关控制模块U3，电性连接所述开关电源模块 U4输入端；及
一过流保护模块U2，电性连接所述开关电源模块U4的输出端及所述第二开关控制模块U3的输入端；
其中，所述第一开关控制模块U1、第二开关控制模块 U3及过流保护模块U2均电性连接所述控制单元以传递控制信号。
进一步地，所述第一开关控制模块U1、第二开关控制模块U3均采用光电耦合器，所述开关管采用但不限于N沟道 MOSFET或P沟道MOSFET。

第三方面，本发明公开了一种洗衣机集成电路，集成了如上所述的双级升压高频电源拓扑结构的电路。
与现有技术相比，本发明的优点和积极效果在于：
本发明提出一种新的双级升压高频电源拓扑结构，实现体积小型化；该高频电源拓扑结构可以自激震荡进行能量传输，可通过控制单元控制BOOST升压开关，当输入传输能量较低时，只采用自激推挽电路升压，当传输能量比较大时，采用升压互补间歇式协作方式，降低功耗。
