什么是变频电源?
Release Date:2010-11-16 Views:2129
经过AC-DC-AC变换的双逆变电源称为变频电源,它有别于用于电机调速用的变频调速控制器,也有别于普通交流稳压电源。变频电源的主要功用是将现有的交流电网电流变换成所需频率的稳定的纯净的正弦波电源。理想的交流电源的特点是频率稳定、电压稳定、内阻等于零、电压波形为纯正弦波(无失真)。变频电源十分接近于理想交流电源,因此,先进发达国家越来越多地将变频电源用作标准供电电源,以便为用电器提供最优良的供电环境,便于客观考核用电器的技术性能。
      变频电源主要有二大种类:电晶体放大型和PWM开关型。DP系列变频电源,以微处理器为核心,以PWM方式制作,正弦脉宽调制等技术,使单机容量可达1000KVA,以隔离变压器输出来增加整机稳定性,具有负载适应性强、输出波形品质好、操作波形好、操作简便、体积小、重量轻等特点,具有短路、过流、过压、过热等保护功能,以保证电源可靠运行。
