摘要： An inverter apparatus includes an inverter circuit, a capacitor, and a control unit. In the first control mode, the control unit shifts a phase of at least one of PWM signals of three phases such that a time period during which polarities of output voltages of three phases are the same is shorter in the first control mode than the time period in the second control mode; and controls the inverter circuit so as to supply a direct current to the three-phase AC motor as a d-axis current by outputting the PWM signals of three phases, each having a phase after the phase shift processing. In the second control mode, the control unit controls the inverter circuit so as to supply an alternating current to the three-phase AC motor by outputting the PWM signals of three phases, each having a phase before the phase shift processing.

摘要： When starting a screw-type air compressor in sub-zero conditions, current spikes are mitigated by detecting an over-current condition and/or a below-threshold temperature, and a warm-up routine is initiated in which compressor motor speed is ramped in a sawtooth fashion between two speeds that are substantially lower than a nominal operating speed of the compressor motor. In this manner, the internal components of the compressor are warmed prior to fully starting the compressor, which mitigates current spikes, reduces blown fuses, and extends the life of the compressor motor and other compressor components.
摘要翻译：当在零零以下条件下启动螺旋式空气压缩机时，通过检测过电流状态和/或低于阈值的温度来减轻电流尖峰，并且启动预热程序，其中压缩机电动机转速在在两个速度之间的锯齿形式基本上低于压缩机马达的标称操作速度。以这种方式，在完全启动压缩机之前对压缩机的内部部件进行加热，这减轻了电流尖峰，减少了熔断熔断器，延长了压缩机电机和其它压缩机部件的使用寿命。

摘要： An adder adds a phase θplus, which is n times a size of 60 degrees, to a phase output from a phase switching unit and outputs the phase as a voltage command phase θ. A voltage generation unit generates voltage command value based on the voltage command phase output by the adder and outputs the command value. A drive-signal generation unit, based on an output from the voltage generation unit generates drive signals corresponding to respective switching elements of an inverter, and outputs respective generated drive signals to the corresponding switching elements of the inverter, and generates a high-frequency AC voltage in the inverter.

摘要： An apparatus for warm up control of an autonomous inverter-driven hydraulic unit has a warm up control section and a switch section. The warm up control section performs a predetermined process using a current speed and current pressure as input information and outputs a first switch command. The switch section is controlled by the first switch command so as to control on/off of power supplied to a fan motor. The apparatus causes an oil temperature to quickly rise to a level where a hydraulic unit driven by a hydraulic pump can work in an optimum condition.
