本文设计了一种基于现场可编程门阵列(FPGA)的用于虚拟同步电机(VISMA)的电流控制器,它是一个具有同步电机性能的并网逆变器。设计并实现了具有FPGA电流控制器的VISMA系统。系统的信号链是完全数字化,减少了标定过程的代价,并增加了系统的集成度。文中对PWM控制的逆变器电流跟踪性能及FPGA中所实现的滞环电流控制算法做了测量和比较。 This paper designs a current controller based on field programmable gate array (FPGA) for virtual synchronous motor (VISMA), which is a grid-connected inverter with synchronous motor performance. VISMA system with FPGA current controller is designed and implemented. The signal chain of the system is completely digitized, reducing the cost of the calibration process and increasing the system’s level of integration. In this paper, the current tracking performance of PWM inverter control and hysteresis current control algorithm implemented in FPGA are measured and compared.
