摘要：
Due to the increasing performance and decreasing price of microcontrollers in recent years, applying a high sampling frequency has become more feasible in modern control that is known as multisampling technology. The first motivation to use multisampling is emulating the analog control, thereby reducing the control delay and improving the stability of power electronics controllers. On the other hand, more information can be acquired from the multisampled current/voltage, which helps to save the cost and improve the reliability. In this article, a review of the multisampling application in power electronics converters is provided. Starting from the control delay analysis in single/double-sampling control, the modeling, implementation, and related control strategies are given when using multisampling pulsewidth modulation. Then, based on the multisampled data, the applications in condition monitoring and parameter estimation are discussed. Finally, perspectives on challenges and future trends are discussed.
