Description

一种半桥拓扑高压静电电源
技术领域
本发明涉及现代电力电子技术，特别涉及一种高压静电电源，其适用于高压静电除尘和油烟净化领域中的特殊应用。
背景技术
静电除尘是利用高直流电压产生电晕放电，使空气电离后产生正离子和负离子，带电的空气尘粒在经过离子箱时被静电场吸附在集尘板上，达到空气净化的效果。静电除尘设备所用的电源具有将低压输入转化为高压输出的功能，用以向静电除尘设备的高压电场提供所需的高电压。由于该电源具有高压电路，跟常规开关电源相比，对电路不同地之间的隔离，反馈回路的实现，电源可靠性等方面实现难度高。另外，不同应用场合对高压输出在短路和拉弧时的电流和持续时间要求不同，一般电路很难实现。
发明内容
为了解决上述目的，本发明提供一种电路简单易调试，输出电压高，输出功率大的高压静电电源。
为了实现上述目的，本发明提供的技术方案是：一种半桥拓扑高压静电电源，包括高压侧和低压侧，所述低压侧的输入端设置有整流滤波电路，所述整流滤波电路是输出端连接有半桥拓扑频率调节电路，所述半桥拓扑频率调节电路还连接有控制单元，所述高压侧连接有电流/电压采集电路，电流/电压采集电路的输出端与所述控制单元连接。
在上述技术方案的基础上，进一步的，所述半桥拓扑频率调节电路包括半桥集成芯片IR2153，所述半桥集成芯片IR2153的HO引脚以及LO引脚连接有MOS管。
作为优选的技术方案，所述控制单元为单片机。
在上述技术方案的基础上，进一步的，所述单片机通过光耦与所述半桥集成芯片IR2153连接。
作为优选的技术方案，所述整流滤波电路中的整流电路为全桥整流电路或全波整流电路或倍压整流电路。
进一步的，所述高压侧设置有两路输出端。
本发明相对于现有技术的有益效果是：该半桥拓扑高压静电电源通过在低压侧设置半桥拓扑频率调节电路，通过控制单元控制半桥拓扑频率调节电路实现恒压输出，实现高压静电电源的闭环控制，即根据高压侧反馈的电压和电流值，通过改变半桥集成芯片的工作频率实现开机软启动和运行中的恒压输出，通过启/停信号实现短路/拉弧等工况时的过流保护。
附图说明
图1是本发明中半桥拓扑高压静电电源模块示意图；
图2是本发明中半桥拓扑高压包功频曲线；
图3是本发明中半桥拓扑频率调节电路图。
具体实施方式
下面结合附图对本发明的具体实施方式作进一步说明。在此需要说明的是，对于这些实施方式的说明用于帮助理解本发明，但并不构成对本发明的限定。此外，下面所描述的本发明各个实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互组合。
如图1所示，本发明提供一种半桥拓扑高压静电电源，该高压静电电源包括高压侧和低压侧，低压侧为输入端，高压侧为输入端，输入端输入交流电，输出端输出高压直流电，输出端可支持双输出，比如：8KV+4KV。
低压侧的输入端设置有整流滤波电路，其中整流电路包括但不限于：全桥整流，全波整流，倍压整流。
整流滤波电路是输出端连接有半桥拓扑频率调节电路，所述半桥拓扑频率调节电路还连接有控制单元，所述高压侧连接有电流/电压采集电路，电流/电压采集电路的输出端与所述控制单元连接。在本实施例中，控制单元采用单片机，具体的采用型号为STM32F103的单片机，在此需要说明的是虽然该实施例中采用该型号的单片机，但本发明的保护范围不局限于此，其他型号的单片机或者控制芯片均在本发明的保护范围内。
半桥拓扑频率调节电路包括半桥集成芯片IR2153，所述半桥集成芯片IR2153的HO引脚以及LO引脚连接有MOS管。
本发明的半桥拓扑高压电源的上下MOS管IR1和IR2的导通周期分别是50％，通过调节开关频率实现输出恒压。如图2所示：在频率f0点(约30KHz)，输出功率达到最大值Pmax。当频率小于f0，频率越小输出功率越小。当频率大于f0，频率越大输出功率越小。出厂调试时，选择略大于f0的f1点为满载工作频率点，实际工作区间(包括轻载和空载)为f0点右侧阴影区。
本发明的半桥拓扑高压电源的频率调节电路图如图3所示：半桥集成芯片为IR2153，通过自举电路D5，C2实现半桥上下MOS管的驱动，脉宽占空比都是50％。开关频率由R1和C1决定，单片机通过给光耦OP1施加不同的驱动电压，可以间接改变R1等效电阻的阻值，从而实现调节IR2153的频率。当单片机检测到过流信号时，通过光耦OP2可以关断IR2153的输出。
本发明的半桥拓扑高压电源开机缓启动过程为：上电时先给光耦OP1施加一个较大的驱动电压，再逐步降低该电压，半桥集成芯片IR2153的输出频率表现为由大转小，对照功频曲线，输出功率由小转大，电压缓慢上升，可以降低开机冲击电流，用单片机实现高压静电电源的闭环控制，即根据高压侧反馈的电压和电流值，通过改变半桥集成芯片的工作频率实现开机软启动和运行中的恒压输出，通过启/停信号实现短路/拉弧等工况时的过流保护。
电源输入电压交流220V，高压输出直流6KV及以上，最高可以到25KV，可以是单输出，也可以是双输出。高压输出可以并联高压瓷片电容用于储能，提升静电离子箱对灰尘放电的瞬间功率。
以上结合附图对本发明的实施方式作了详细说明，但本发明不限于所描述的实施方式。对于本领域的技术人员而言，在不脱离本发明原理和精神的情况下，对这些实施方式进行多种变化、修改、替换和变型，仍落入本发明的保护范围内。
