电机用电压转换控制装置
摘要：
一种电机用电压转换控制装置，其为实施对在控制多个电机(16、17)的电机控制电路(14、15)与电源(10)之间的、电压转换电路(12)的电压转换控制的控制装置(18)，其特征在于，具备：取样单元(13a、18l、18m)，其对电压转换后的直流电压进行取样；目标电压设定单元(18e、18f)，其设定多个电机(16、17)的目标电压(VHT1、VHT2)；选择单元(18j)，其从多个目标电压(VHT1、VHT2)中选择由电压转换电路(12)转换的目标电压(VHT)；产生单元(18k)，其根据目标电压未被选择的电机中的任意一个电机的门信号(GS1)或者(GS2)而产生取样正时(TS)；控制单元(18g)，其在电压转换控制的每个取样正时请求(DS)时，利用根据取样正时(TS)而由取样单元(13a、18l、18m)所取样的直流电压，来实施电压转换控制。
摘要（英）：

A control device performs voltage conversion control on a voltage conversion circuit between a power supply and motor control circuits which control a plurality of motors. The control device includes sampling units for sampling a DC voltage after voltage conversion, target voltage setting units for setting target voltages VHT1 and VHT2 of the plurality of motors, selection unit for selecting a target voltage VHT to be converted by the voltage conversion circuit from a plurality of target voltages VHT1 and VHT2, generating unit for generating a sampling timing TS on the basis of a gate signal GS1 or GS2 of one of the motors with the target voltage which has not been selected, and control unit for performing the voltage conversion control using the DC voltage sampled by the sampling units at the sampling timing TS in response to each sampling timing request DS in the voltage conversion control.
