大型或特大型化工企业一般具有生产联系紧密、物料平衡难度大、工艺流程复杂、公用工程联系紧密、生产过程高温高压、物料有毒有害、易燃易爆、设备单机价值高、恢复开车时间长等特点。由于供电量大且集中，这类企业往往在企业内部形成相对独立的6一35kV企业配电网，其供配电系统具有供配电网络系统复杂、电力负荷密度大、供电可靠性要求高、在用电气设备状态水平参差不齐、使用环境由于污染腐蚀而较为恶劣、供配电线路以电力电缆为主等特点。
随着企业的不断发展，电网规模相应扩大，电网结构也日趋复杂，由于上述特点的存在，化工企业的供配电系统遭受雷击、设备事故、操作事故和故障等因素发生的机率也相应增加，这些每次故障和事故都给企业供配电系统带来一定的影响和冲击。
除了直接造成停电事故外，更多的表现为对供电系统电能质量的影响，主要体现在电压波动等。每次的电网冲击和电压波动，都会对化工生产装置造成很大的影响，引起许多重要电机停机，导致生产过程紊乱，使生产装置停车。企业电网经过四十多年的发展，已成为一个由发电、变电、输电、配电和用电等设备和相应的辅助系统，按规定的技术、经济要求组成的一个内部电力网。
变频器（Variable-frequency Drive，VFD）是应用变频技术与微电子技术，通过改变电机工作电源频率方式来控制交流电动机的电力控制设备。开关电源电路提供变频器的整机控制用电，是变频器正常工作的先决条件。维修变频器，就得先搞明白开关电源电路。
变频器应用的开关电源电路，为直一交一直型的逆变电路，是一种电压和功率的变换器，将直流电压和功率转换为脉冲电压，再整流成为另一种直流电压。输人、输出电压由开关变压器相隔离，开关变压器起到功率传递、电压/电流变换的作用。开关变压器为降压变压器。开关电源的特点如下：
1）开关电源的振荡和调压方式是利用改变脉冲宽度或周期来调整输出电压的，称为时间比例控制，又分为PWM（调宽）和PFM（调频）两种控制方式。
2）从电路的能量转换特性看，可分为正激和反激两种工作方式。开关管饱和导通时， 二次绕组连接的整流器受反偏压而截止，开关变压器的一次绕组流入电流而储能〈电磁转换）。开关管截止时，二次绕组经负载电路释放电能（磁电转换）。正激方式则与此相反， 实际应用不多。
3）从开关变压器的一次电路结构来看，有分立元件构成的和集成振荡芯片构成的两种电路形式。因而从振荡信号的来源看，又分为自激（分立零件）和他激式（IC电路）开关电源。两种电路结构都有应用。
4）开关管有采用双极型器件和采用场效应晶体管的。
5）小功率变频器采用单端正激式电路，大、中功率变频器常采用双端正激式电路。一般变频器的开关电源，常提供以下几种电压输出：CPU及附属电路、控制电路、操作显示面板的+5V供电；电流、电压、温度等故障检测电路、控制电路的±15V供电；控制端子、工作继电器线圈的24V供电。四路相互隔离的约为22V的驱动电路的供电，该四路供电往往又经稳压电路处理成+15V、 -7.5V的正、负电源供驱动电路，为IGBT逆变输出电路提供激励电流。
任何电子设备，电源电路的故障率总是相当高的一因其要提供整机的电源供应，负担最重。变频器的开关电源电路，形式上比较单一，结构上也比较简单。但是简单电路也可能会产生疑难故障。开关电源的检修不像线性电源那么直观，电路的任一个小环节一振荡、稳压、保护、负载等出现异常，都会使电路出现各种各样的故障现象。
通上电后无反应，操作显示面板无显示，变频器好像没通电一样。测量控制端子的控制电压和10V频率调整电压都为0，测量变频器主接线端子电阻正常，那么大致上可以断定问题是出在开关电源电路了。
