合成结果显示平均30% FPGA的用法,相当于6系统为一门轴控制进一步的轴控制器可实行FPGA没有硬件改造利用平行,结合时序结构。由于它的自然的并行设计、开发取得了全面延误的时钟周期为12个数据处理在每个样本的计算。它还必须考虑到所有的本构块工作,因此在平行延迟是最小的。作为对照,考虑到一个标准的商用定点DSP从德州仪器(2005年),这相当于在TMS320C5409成本和整合复杂度的FPGA在这种情况下,全面加工时间的时钟周期2050年显著高于FPGA实现。现在,考虑到一个平等的时钟频率的两种选择,我们50MHz延迟在FPGA为240坏死性涎腺化生而延迟的DSP在每个采样计算41女士。
为了估计FPGA实现绩效、表5给出了最小环路更新理论为FPGA,DSP和商业上可用控制器Galil 18 * 0不同数量的轴。在加利福尼亚州的最低要求timerelated环路更新,分辨率和进给速度控制器,给出了(18)为(公式20)。
表6显示几个最小环路更新时间为4个不同的要求:喂,45000和1500,6毫米/分钟,三个控制器的决议,0.05,0.1 0.01毫米。从表5和6个,可以看出,Galil 18_0控制器适用于一些案例中,而DSP-based控制器适用于别人,以及FPGA实现相配的所有情况。

Characteristics of modern power electronics laboratory bench:
(1) The experimental apparatus hanging structure, can be freely combined according to the different experimental content, so the structure is compact, easy to use, full-featured, good overall performance, power electronics technology in a device, semiconctor converter technology "courses offered experimental project.
(2) the experimental device small footprint, the conservation laboratory space, no need to set the power control panel, cable trenches, concrete barrier, may rece investment in infrastructure; experimental device only three-phase four-wire power can be put into use, the laboratory the construction period is short and quick.
(3) The device layout is reasonable, beautiful shape, clear panel diagram, clear and intuitive. Experimental cable using a strong, the weak separate the pistol plug the two not INTERFIX avoid strong electrical access the weak electrical equipment, causing equipment damage; experimental line connection is safe, reliable, quick and easy; addition to the power control panel, pendant also provided laboratory tables can be placed on the desktop oscilloscope experimental apparatus, comfortable, convenient operation. The bottom of the bench mounted wheels and stainless steel mounting adjustment mechanism to facilitate the mobile and fixed.
(4) control panel power supply three-phase isolation transformer isolated, with voltage leakage protection device and current leakage protection device, effectively protect the personal safety of the experimental operation, and to create the security conditions for the open laboratory.
(5) pendant panel is divided into three wiring holes, strong power, weak and waveform observation wells, three obvious difference.
(6) experimental line select typical line, fully compatible with the teaching content, and to meet the curriculum requirements
Maintenance and repair of power electronics laboratory bench:
School power electronics laboratory bench often students use, easy to damage, bench maintenance and repair is a very important thing.
