    • PURPOSE:To PWM-control in a simple calculation in high accuracy at a high speed by calculating PWM waveform pattern data stored in a pattern generator in response to a control rate and angular frequency. CONSTITUTION:PWM waveform pulse pattern data is output from pulse pattern generating means 5 in response to the number of carrier pulses, the pattern data is converted by pattern data converting means 6 in response to an angular frequency command, and applied to a PWM waveform calculator 7. The calculator 7 regulates the pattern data in response to a control rate and the angular frequency, and applies as data for forming the PWM waveform to a gate circuit 8. The circuit 8 obtains a PWM waveform voltage signal and supplies it to a voltage type inverter 9.

    • PURPOSE: To enhance the conversion efficiency of an inverter by securing a special switching element to the prescribed state during the prescribed phase, and controlling the other switching element ON and OFF, thereby reducing a current ripple and preventing a noise from occurring.
      CONSTITUTION: An inverter 1 has switching elements 1a∼1c, and supplies a voltage therefrom to a load 2. The specific switching element connected to the specific output terminal is secured to the specific state so that the specific output terminal becomes an anode during the phase of 120° or lower with the output terminal of the inverter 1 for outputting a current to be flowed to the phase of the maximum ideal positive voltage, and the other switching element is controlled ON and OFF, thereby approximating the output current waveform to an output current command waveform.
