Abstract: An apparatus includes a DC-link, a voltage converter, a bus voltage controller, and a supervisory controller. The voltage converter is configured to convert a first DC voltage into a second DC voltage based on a command signal and based on an adjustment signal and to supply the second DC voltage to the DC-link. The bus voltage controller is configured to iterate calculation of the adjustment signal to communicate each iterated calculation of the adjustment signal to the voltage converter. The supervisory controller is configured to iterate calculation of the command signal and to communicate each iterated calculation of the command signal to the voltage converter and to the bus voltage controller. A frequency of the bus voltage controller to communicate each iterated calculation of the adjustment signal is higher than a frequency of the supervisory controller to communicate each iterated calculation of the command signal.

Abstract translation: 一种装置包括直流链路，电压转换器，总线电压控制器和监控控制器。 电压转换器被配置为基于指令信号并且基于调整信号将第一直流电压转换为第二直流电压，并将第二直流电压提供给直流链路。 总线电压控制器被配置为迭代调整信号的计算，以将调节信号的每次迭代计算传送到电压转换器。 监控控制器被配置为迭代命令信号的计算，并且将命令信号的每个迭代计算传送到电压转换器和总线电压控制器。 总线电压控制器的频率通过每个迭代计算的调整信号高于监控器的频率来传达每次迭代计算的命令信号。
