摘要：
Zero-Voltage-Transition (ZVT) DC-DC converters with active snubber can be conveniently employed in photovoltaic applications requiring high efficiency and isolation transformer. In order to improve the dynamic response of the converter, a Feed-Forward current controller is proposed and compared with the conventional proportional-integral controller. The Feed-Forward control is achieved using the equivalent converter electrical model and the desired current reference, calculates the expected operating point; then, a suitable correction term is added to compensate for the current error. The control design is first validated through simulations and, finally, verified by experimental results on a laboratory prototype.
