Due to the increasing performance and decreasing price of microcontrollers, applying a high sampling frequency becomes more feasible in modern control. This approach is known as multisampling technology. This paper tries to give an overview of the multisampling application in power electronics converters as it enables a lot of opportunities. First, the multisampling can reduce control delays and thereby break bandwidth limitations in power electronic controllers. Secondly, a smarter control strategy can be realized with more current, voltage and system information acquired through multisampling techniques. However, this approach may also introduce two major drawbacks: risk of dead bands and high-frequency switching ripples, which may degrade the system stability margin. To address these issues, different solutions are explored and illustrated in this paper.
