【应用】高性能电解电容助力变频器运行更加稳定
在工业控制领域，为实现环保节能和电气改造，变频器已经越来越多的应用在电机控制领域。电解电容作为变频器内部滤波和直流支撑的关键元件，在平滑脉动电流和降低纹波电压起到至关重要的作用。
图1：变频器功率拓扑电路
图1所示为变频器功率拓扑电路。图中标注的电容主要起平滑脉动电流的作用，输入端交流电通过三相整流，将交流整成直流，再通过逆变电路输出需要的交流电。整流桥后端的电解电容在平波的同时吸附掉大量中低频谐波，为后面的DC-AC部分提供稳定的输入直流电流。该处输入的直流电流的纹波减少，将从源头对输出端降低纹波起到关键性的作用。
在实际应用中，变频器通常安装在工厂车间中，环境中粉尘或水汽较多，如果要保证变频器的正常长时间的工作，核心在于保证内部功率转换单元的正常平稳运行。这就要求内部的电容具有长期的高稳定性以及能适应各种户外的恶劣环境。
意大利KENDEIL是专业生产大功率逆变器应用电子元器件的领先生产商，有超过37年的设计生产经验。其电容产品不仅拥有自己的铝箔生产线，还使用先进的集成技术和生产工艺，并且定期进行技术革新。图2所示为Kendeil的K074螺栓型电解电容系列的示意图。
图2：K074螺栓型电解电容系列
K074螺栓型电解电容的主要特点如下：
• 大容量：2200uF~15000uF
• 高耐压：400VDC
• 最高纹波电流可达100A
• 在85℃工作温度，正常电压的情况下寿命超10万小时
Kendeil的K074螺栓型电解电容应用在变频器中，具有以下几点优势：
1）电容容量在恶劣的环境下容量衰减幅度小，吸收电路纹波的能力强，电容的寿命也更长；
2）电容的高温特性好，在工作中，随着温度的升高其漏电流变化幅度很小；
3）电容的低温特性好，在北方环境温度较低的地方，其容量能够保持相对恒定，保证低温时设备能够正常运转。
从以上优势可见，K074螺栓型电解电容能够适应于变频器严苛地恶劣环境中，且具有应对南北方不同温度条件的很好的性能，为开发人员省去多器件设计的烦恼，是变频器设计理想的选择。

【选型】如何为变频器选取阻值合适的预充电电阻？
充电电阻串接在充电回路中，起通电瞬间限流充电，以保护整流器等一些输入回路器件的作用，也叫缓冲电阻或启动电阻。本文介绍变频器预充电电阻选取方法。ISABELLENHUTTE设计生产BRK系列制动和预充电电阻器阻值10-400Ω，额定功率100W，脉冲功率1kW/s。BRQ系列制动和预充电电阻器阻值1-300Ω，额定功率300W，脉冲功率3kW/s。

变频器滤波长寿命电解电容的损坏的原因
铝电解电容器通常是由金属箔（铝/钽）作为正极，金属箔的绝缘氧化层（氧化铝/钽五氧化物）作为电介质，电解电容器以其正电极的不同分为铝电解电容和钽电解电容器。铝电解电容器的负电极由渍过电解质液（液态电解质）的薄纸/薄膜或电解质聚合物构成；钽电解电容器的负电极通常采用二氧化锰。由于均以电解质作为负电极，长寿命电解电容因而得名。

在传统的变频器和逆变器中母线电容都选用的电解电容，目前新型的逆变器中都选择薄膜电容，请问薄膜电容相比电解电容都有哪些优势？
目前集中型和组串式逆变器越来越多的选用薄膜电容，其原因是：（1）薄膜电容较电解电容耐压可以做到更高，电解电容最高只能做到450V，而薄膜电容最高可做到1500V甚至更高，在高压系统中无需串联；（2）薄膜电容较电解电容耐高温性能更高；（3）薄膜电容比电解电容寿命更长。
