由于开关电源的设计是多变量的迭代过程,因此采用传统方法人工设计开关电源不仅工作量大、效率低,而且难于实现优化设计。近年来,随着电源技术的发展和计算机应用的普及,开关电源计算机辅助设计与仿真作为国际上电源领域的一项新技术,受到了人们的高度重视。目前,软件已成为优化开关电源设计的关键技术。 Because the design of the switching power supply is a multivariable iterative process, it is not only heavy workload, low efficiency, but also difficult to realize the optimal design by artificially designing the switching power supply by using the traditional method. In recent years, with the development of power technology and the popularization of computer application, the computer aided design and simulation of switching power supply has been paid great attention by people as a new technology in the field of power supply in the world. At present, the software has become the key technology that optimizes the switching power supply design.
