【应用】DB35三相整流桥应用于通用型变频器中，漏电流小于10uA
通用型变频器在电机驱动控制有明显的节能效果，节电率可达20~60%，被广泛应用于风机、泵类负载等交流电机驱动中。通用型变频器系统原理如图1所示，三相交流电压经过三相整流桥整流、PFC功率因素校正、滤波平滑后成为稳定的直流高压，通过DC-DC升压变换后为后级逆变器提供符合要求的直流电压，后级三相逆变器根据DSP控制单元的输出驱动脉冲产生频率变化的正弦电压驱动电机的运转（注：中间Brake Chopper为制动斩波器，用于消耗电机处于再生发电状态时反馈回直流侧的过高电压）。整个功率单元电压转换为AC-DC-AC。
图1. 变频器系统原理框图
图2. 三相整流桥应用电路图
如上所述，变频器AC- DC单元的转换主要由整流器完成，其整流原理如图2所示，利用二极管的单相导通性，三相交流电压经过整流桥后成为直流脉动电压，经过电容、电感滤波后，成为直流电压。对于中小功率的变频器采用三相整流桥即可获得比较理想的转换效率，在选择三相整流桥器件时，可以挑选更低的正向压降和漏电流器件，以进一步优化变频器效率。针对此处的应用，推荐DIOTEC（德欧泰克）DB35系列三相整流桥，该系列整流桥正向压降VF小于1.05V（@IF=17.5，25℃），漏电流IR小于10uA，可以进一步优化整流电路的转换效率，提高产品的性能。产品外观、尺寸如图3所示。
图3. DB35系列三相整流桥
DB35系列三相整流桥最大重复峰值反向电压VRRM从50~1600V，最大交流输入电压有35~1000V，型号包括DB35-005，DB35-01，DB35-02，DB35-04，DB35-06，DB35-08，DB35-10，DB35-12，DB35-14，DB35-16等，具体产品规格如下表所示，对于一般的380V三相交流电，整流后电压约为510V，可以挑选DB35-08、DB35-10、DB35-12、DB35-14、DB35-16，以保障1.5~3倍的电压裕量。
DB35系列三相整流最大整流输出电流IFAV为35A，最大重复峰值电流IFRM达120A（@f>15Hz，Tc=55℃），最大可承受正向峰值浪涌电流IFSM达450A（@半正弦波，50Hz（10ms）），可有效的应对变频器开机启动时浪涌电流的冲击。反向恢复时间trr典型值1500ns，能有效的降低市电电压换相时波形失真，减少谐波的产生。端子到外壳绝缘电压大于2500VRMS，结壳热阻小于1.8K/W，具有优良的散热性，有利于降低器件发生热失控的风险。DB35系列三相整流桥通过了UL认证（认证文件E175067），无铅符合RoHS、REACH标准，阻燃等级UL 94V-0，重量约21g，运行结温-50~＋150℃，是一款可靠性高、性能优良、绿色环保的器件。
