Abstract

A Piecewise Digital Control method is presented in this paper to improve the converter characteristics especially the efficiency. By combining more than one control method or/and compensators in a single converter controller, improved performance may be achieved. Piecewise control opens the possibility of combining advantages of different control schemes and preventing or minimizing their disadvantages. In this paper, by combining the asymmetric control and the duty-cycle-shifted control in a new piecewise control scheme, the performance and efficiency of half-bridge DC-DC converter with high switching frequency and wide Input voltage range can be Improved, without adding additional components. The proposed control is theoretically analyzed and its implementation considerations are discussed. Experimental results are also presented. © 2005 IEEE.
