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