一、 前言

}l Dm+E#OxC*\\

我国目前还有很多地区交流电网的供电质量不太高，表现为经常过欠压、瞬时跌落、浪涌和尖峰干扰较多等。而随着科技和经济的发展，信息技术和微电子技术的应用，大量用电设备对供电质量的要求越来越高，因而，电力稳压器已成为许多电子设备（如计算机、通信设备、广电发射设备、医疗设备等）和机电设备（如数控机床、注塑机等）不可缺少的供电装置。

目前，许多地方还大量使用机械碳刷调压的稳压器和参数调整型稳压器。机械碳刷型稳压器的主要缺点为：碳刷工作寿命短、需要经常维护，大电流时易产生火花，引起电磁干扰，机械调压响应时间长，三相不能分调等等。参数调整型稳压器的主要缺点为：效率低、负载适应性差、波形失真大、温升高等等。上述类型的稳压器有着许多缺点和不足，已远远不能适应现代科技发展的需要。

在现代电源领域，要保证电源装置能做到精密地控制和可靠地运行，必须采用电力电子技术，在装置中使用电力半导体器件（可控硅）。电力半导体器件具有效率高、控制性能好、体积小、重量轻、使用可靠等许多优点。因此，采用电力电子技术对电力稳压器进行升级换代， 已是目前大功率电力稳压器的主要发展方向。

上海潘登电源公司及时分析了市场对新一代大功率稳压电源的需求，研制成功DBW5/SBW5型系列大功率无触点补偿式电力稳压器（以下称潘登5型稳压器），本文将就潘登5型稳压器的系统结构、工作原理及突出优点作一简单介绍。

潘登5型无触点补偿式稳压器主要由补偿电路、调压电路、检测控制电路、输入采样电路、输出采样电路、延时输出电路、保护电路等单元组成。

其工作过程为：当输入电压波动或负载变化时，通过采样电路获取反馈电压，经检测控制电路与基准电压进行比较判断，然后输出控制信号，控制调压电路中相应的可控硅导通，使补偿电路产生极性和大小不同的补偿电压，达到稳定输出电压的目的。同时，检测控制电路还对保护电路和延时输出电路进行控制，产生相应的动作。 （2）工作原理
