    • In a power converting apparatus having a plurality of phases on an AC side and configured to perform conversion between DC power and AC power, a current detector detects currents flowing through a DC source line through which a plurality of phase currents commonly flow. A control unit sets a current detection period and a succeeding current control period in each successive control cycle. Using first gate signals based on reference gate signals for PWM control, the control unit calculates values of the individual phase currents from the first gate signals and the detected currents during the current detection period. Then, during the current control period, the control unit performs PWM control using phase voltage commands generated by correcting phase voltage target values so as to cancel out voltage errors that occur during the current detection period.
    • 在具有交流侧多相的电力转换装置中,电流检测器检测流经多个相电流通过的直流电源线的电流。 控制单元在每个连续的控制周期中设置电流检测周期和后续电流控制周期。 使用基于用于PWM控制的参考栅极信号的第一栅极信号,控制单元在当前检测周期期间从第一栅极信号和检测到的电流计算各个相电流的值。 然后,在当前控制期间,控制单元使用通过校正相电压目标值而产生的相位电压指令来执行PWM控制,以抵消在当前检测周期期间发生的电压误差。
