为了满足多通道直流电源同时激活多种宏纤维复合材料的需求,提出了一种基于光谱分离的单输入单输出变压器的多通道可调直流电源。增强包含多个频带的混合信号以获得不改变频带的高压信号。然后使用几个频率选择电路从高压信号中分离不同频带中的各个信号。最后,分别对这些信号进行整流和滤波以获得多通道直流电压。从理论上分析了该方案的可行性,并通过仿真进行了验证。包含多个频段的混合信号由MCU(微控制单元)构建,并使用推挽升压电路进行升压,使用低通,带通和高通频率选择电路来获得各个高压信号的不同频率实验结果证明该方案的各个部分运行可靠,输出稳定可调。
To meet the need of multi-channel DC power supply to activate multiple macro fiber composite (MFC) materialsimultaneously, a novel multi-channel adjustable DC supply using single-input single-output transformer based on spectralseparation is proposed. A hybrid signal containing multiple frequency bands is boosted to obtain a high-voltage signalwithout bands change. Several frequency selection circuits are then used to separate individual signals in different frequencyband from the high-voltage signal. Finally, these signals are rectified and filtered respectively to obtain multiple channelDC voltages. The feasibility of the proposed scheme is analyzed theoretically and verified by simulation. The hybrid signalcontaining multiple frequency bands is constructed by MCU (Micro Control Unit) and boosted using push-pull boost circuit.Low-pass, band-pass and high-pass frequency selection circuits are used to obtain the individual high-voltage signal indifferent frequency bands, and the amplitude frequency response characteristics of these filters are simulated using PSpice.Experimental results prove that each part of the scheme runs reliable and the output is stable and adjustable.
