本文首先阐述了电力电子学的目标和应用，接着简要介绍了电力电子学的历史和重要的功率半导体器件的列表。还简要介绍了交流电机和电力系统的相关领域。综述了电子电路非线性动力学的发展。然后，通过传统的平均和线性化方法（预测稳定性）和基于非线性映射的方法（揭示分岔、次谐波和混沌），对典型的功率变换器（受控降压dc-dc变换器）进行建模。讨论了电力电子系统状态方程不连续引起的数值问题。最后，对未来可能的应用进行了展望。
This review paper starts by setting out the aims and applications of power electronics, and continues with a brief history and a list of the important power semiconductor devices. The related areas of ac machines and power systems are also briefly visited. The development of nonlinear dynamics in electronic circuits is reviewed. Then a typical power converter, a controlled buck dc-dc converter, is modelled by the conventional method of averaging and linearisation (which predicts stability), and by a nonlinear map based method, which reveals bifurcations, subharmonics and chaos. The numerical problems caused by the discontinuities in the state equations of power electronics are discussed. Finally, some possible future applications are considered.
