    摘要： The invention provides an electric power converter system which uses a standard low-priced control processor and is suitable for improving the voltage utilization factor in the output voltage. D-axis and q-axis voltage commands and a rotation angle .theta. defining a voltage command vector on a rotating coordinate system are input to a voltage calculation circuit. The voltage command vector is transformed in a rotating coordinate transformation unit into a .alpha. axis and .beta. axis voltage commands to be defined relative to stationary coordinate system. A judgment unit determines which section contains the voltage command vector, from among three sections on the stationary coordinate system having one axis thereof (.alpha.-axis for example) coinciding with one axis of the three phases. A three phase voltage generation unit then selects a method of calculation on the basis of a result of the section determination, and calculates three phase voltage command values respectively utilizing the .alpha. axis and .beta. axis voltage command values. Since calculation requires only a simple add/subtract and shift operation, a high performance economical power converter system which improves the voltage utilization factor substantially can be realized.

    摘要翻译： 本发明提供一种使用标准低价控制处理器的电力转换器系统，适用于提高输出电压的电压利用率。 D轴和q轴电压指令以及旋转坐标系上定义电压指令矢量的旋转角θ被输入到电压计算电路。 电压指令矢量在旋转坐标变换单元中变换为相对于固定坐标系定义的α轴和β轴电压命令。 判断单元从具有与三相的一个轴一致的一个轴（例如，α轴）的固定坐标系上的三个部分中确定哪个部分包含电压指令矢量。 三相电压产生单元然后基于区段确定的结果选择一种计算方法，并且分别使用α轴和β轴电压指令值来计算三相电压指令值。 由于计算仅需要简单的加/减运算，所以可以实现提高电压利用率的高性能经济型电力转换器系统。

A control apparatus which generates drive signals to drive power devices in the power converter includes: a current reference generator calculates from a torque reference value a d-axis exciting current reference value on the basis of which the ac motor generates a magnetic flux, and a q-axis torque current reference value, the d-axis and the q-axis being orthogonal to each other; a current control circuit generates ac voltage reference values Vu*, Vv* and Vw* from the d-axis exciting current reference value and the q-axis torque current reference value; and a drive signal generator generates drive signals to drive power devices from the ac voltage reference values. Both the current reference generator and the current control circuit are processed digitally by the same arithmetic unit.

    摘要： An inverter system providing both an improvement in the voltage utilization factor and a reduction in the switching loss uses a two-phase switching method. In the inverter system, an .alpha.-axis voltage command value; v.sub..alpha.r and a .beta.-axis voltage command value v.sub..beta.r are input to a stop phase selection means. Six sections are judged based on the values v.sub..alpha.r and v.sub..beta.r to select phases for which it is allowable to stop pulse width modulation control in a two-phase switching method. Then, a phase having the largest absolute value of current is selected among the phases for which it is allowable to stop pulse width modulation control using a U-phase current i.sub.u and a V-phase current i.sub.v. This information is a control mode S. Based on these, two-phase switching calculations are performed by a dead-time compensation calculation means and a pulse width modulation generating means. By doing so, the switching loss can be reduced.
