基于FPGA的单向高频链逆变器设计

Design of High-frequency Link Inverter based on FPGA

针对小功率应用场合,提出了一种基于现场可编程门阵列(Field Programmable Gate Array,简称FPGA)单向高频链(High Frequency Link,简称HFL)逆变器的设计。设计中采用了DC/DC和DC/AC两级变换形式;控制电路利用了FPGA的强大编程能力和控制能力,使得系统的更新非常灵活,能满足各种情况下的应用。通过仿真和实验结果验证了设计的正确性。

A high-frequency link inverter based on FPGA is designed for the application of low-power.The inverter is composed of two stages which are DC to DC and DC to AC converters.The control circuit used digital control method of the powerful programming and control ability of FPGA, made a very flexible system upgrades and can meet different circumstances easily.The simulative and experimental results verify that the design is effective.
