DC/DC CONVERTER

A reactor has one end connected to a neutral point of a transformer and the other end connected to a primary-side power supply. The transformer has almost no effective flux linkage for zero-phase current and has a phase difference between the primary side and the secondary side. A first bridge circu...

More Information
Summary:A reactor has one end connected to a neutral point of a transformer and the other end connected to a primary-side power supply. The transformer has almost no effective flux linkage for zero-phase current and has a phase difference between the primary side and the secondary side. A first bridge circuit and a second bridge circuit are connected to both ends of the transformer, and electric power of the primary-side power supply is controlled by the duty ratio of the first bridge circuit. The switching pattern of the second bridge circuit is phase-shifted in the leading direction and the lagging direction with reference to the switching pattern of the first bridge circuit, thereby achieving control such that soft switching operation can be performed even when the voltage ratio between the primary-side power supply and the secondary-side power supply fluctuates and the amount of transmission power is reduced.
