Deadbeat controller design for a soft-switched high-frequency resonant rectifier

摘要

In this paper, a deadbeat controller design technique is developed for a quantum boost series resonant rectifier (QBSRR) to achieve the fast dynamic responses of the output voltage in the presence of any load variations, and in order to monitor the load information without employing the current sensor, the load estimation method is also derived. By using the information of the load estimation method, the proposed controller gain is automatically adjusted to have the system always keep the very fast dynamic responses. To verify these superior performances, the simulation and experiment are carried out.
