Highly efficient, tightly regulated DC-to-DC converter |
摘要 |
The invention presents a highly efficient, tightly regulated DC-to-DC converter which can be used in various applications, especially multiple output converters. The converter uses a buck converter to produce an intermediate bus voltage. A current-fed double ended circuit, such as bridge or push-pull circuit, couples to the buck converter to provide power to outputs. The double ended circuit operates at about 50% duty. The secondary output filter inductor is not required. With 50% duty cycle operation, the secondary rectifiers are easily controlled by either a self-driven or an external driven circuit. The secondary windings can also be stacked up to simplify the transformer design. In addition, bias voltages needed for control circuitry can also be obtained by adding extra windings to the power transformer and extra rectifier devices.
