The invention relates to DC-DC converter control, and discloses a method to control an output voltage of a DC-DC converter, and voltage control logic operable to generate a voltage command to implement the control method. The method includes: sensing a voltage of a bus of an electric-drive vehicle; increasing a command voltage signal from the sensed voltage to a nominal voltage during a first time period; increasing the command voltage signal from the nominal voltage to a desired voltage during a second time period greater than the first time period; and generating a voltage output based on the command voltage signal.
本公开涉及DC‑DC转换器控制。一种控制DC‑DC转换器的输出电压的方法以及电压控制逻辑单元,该电压控制逻辑单元可操作以生成实现该控制方法的电压命令,该方法包括:感测电动车辆的总线的电压;在第一时间段期间将命令电压信号从感测电压增加到标称电压;在大于第一时间段的第二时间段期间将命令电压信号从标称电压增加到期望电压;以及基于命令电压信号生成电压输出。
