摘要：
Two new hybrid buck type converters are proposed. Compared to the classical buck converter, the proposed topologies provide a negative output voltage, while compared to the buck-boost converter semiconductor voltage stresses are lower. The coupled inductor version has the additional advantage of achieving a smaller conversion ratio for the same duty cycle value. The dc analysis is presented and design equations are developed. Simulation and experimental verifications confirm the feasibility of the new topologies.
