电压变换设备和执行对电压变换设备的电压变换控制的方法
摘要：
本发明涉及电压变换设备和执行对电压变换设备的电压变换控制的方法。控制装置(30)基于扭矩指令值(TR1(或TR2))和电机转数(MRN1(或MRN2))计算升压变换器(12)的电压指令值，并基于计算得到的电压指令值和来自电压传感器(10)的DC电压(Vb)计算NPN晶体管(Q1)的占空比(D_ON_1)。在所述占空比(D_ON_1)被死区时间影响并且所述DC电压(Vb)小于预定设置值的情况下，所述控制装置(30)控制NPN晶体管(Q1，Q2)以在将所述占空比(D_ON_1)固定为1.0时对所述电压进行升压或降压。
摘要（英）：

The invention relates to a voltage changing device and a method for executing a voltage changing control to the voltage changing device. A controller (30) calculates voltage instruction value of a booster converter (12) based on torque instruction value (TR1 (or TR2)) and motor revolution number (MRN1 (or MRN2)) and calculates duty ratio (D_ON_1) of an NPN transistor (Q1) based on calculated voltage instruction value and DC voltage (Vb) of the voltage sensor (10). Under the condition that the duty ratio (D_ON_1) is influenced by dead zone time and the DC voltage (Vb) is less than predetermined value, the controller (30) controls NPN transistor (Q1, Q2) for increasing or reducing the voltage when the duty ratio (D_ON_1) is fixed to 1.0.
