由于成本下降,可再生能源系统的使用正在世界范围内扩大。这些系统需要将直流电源转换为电网同步的交流电源。目前,实现这项任务的逆变器是用分立晶体管设计制造的。TowerJazz半导体公司(TowerJazz Semiconductor Corp.)创造了一种商业化的CMOS工艺,可以阻断高达700伏的电压,有效地消除了将功率逆变器集成到单个芯片上的障碍。本文使用两种拓扑来研究这个过程。第一种是基于单元的开关电容拓扑,首先由Ke Zou提出。第二种是一种新颖的拓扑结构,探索了使用总线作为输入输出系统的优势,就像在数字电路中一样。在这两种拓扑上运行的仿真结果证实了邹的方法所证明的高效性,以及基于总线的系统在输出电压水平上的优势。
Due to their falling costs, the use of renewable energy systems is expanding around the world. These systems require the conversion of DC power into grid-synchronous AC power. Currently, the inverters that carry out this task are built using discrete transistors. TowerJazz Semiconductor Corp. has created a commercial CMOS process that allows for blocking voltages of up to 700 V, effectively removing the barrier to integrating power inverters onto a single chip. This thesis explores this process using two topologies. The first is a cell-based switched-capacitor topology first presented by Ke Zou. The second is a novel topology that explores the advantage of using a bused input-output system, as in digital electronics. Simulations run on both topologies confirm the high-efficiency demonstrated in Zou’s process as well as the advantage the bus-based system has in output voltage levels.
