有源升降压逆变器双模式调制策略研究
Research of an active Buck-Boost Inverter Under Dual Mode Modulation
摘要
Abstract
The inverter used in new energy power generation system should have the ability to adapt a wide range of DC input voltage. Based on the active buck-boost inverter which consists of a full bridge and Boost AC/AC part, two modulation methods were compared: constant boost ratio modulation and dual mode modulation. Along with the relationship of the input DC voltage and the reference AC voltage, the converter completes buck or boost inversion with different equivalent circuits and there are fewer switches working at high frequency in dual mode modulation, which is in favor of the system with high efficiency. The current of the inductor and the current stress of the switches was analyzed in this paper. Experimental results were presented to verify that the proposed topology can achieve dual mode operation with wide range of input voltage.关键词
