Abstract

PURPOSE: To obtain a PWM controller, a voltage utilization factor thereof is improved, by simple circuit constitution by forming the high voltage command of a triple harmonic from a flux command. CONSTITUTION:The flux command of a triple harmonic is divided into three by a frequency divider 19 and used as a flux command while phase is advanced only by 270 deg. by a phase shifter 16 in the flux command of the triple harmonic. An output from the phase shifter 16 is brought to the same phase as the triple harmonic of a voltage command. The output from the phase shifter 16 is multiplied by thc amplitude of a fundamental-wave voltage command, and a value acquire ed by multiplication is multiplied by a fixed coefficient by a coefficient multiplier 18, thus obtaining the voltage command of thc triple harmonic. The voltage command of the triple harmonic and the fundamental-wave voltage command are added, and employed as a voltage command. Thc voltage command is inputted to a comparator 7a, and compared with an output from a carrier generating circuit 9, thus generating a PWM signal.

A fundamental wave voltage command v1 of frequency f is inputted to , and a pulse of frequency 3Nf is outputted. This pulse is used as a clock for the N-divided counter 152, and the ROM 153 outputs sine wave data with a frequency of 3f, which is converted into an analog sine wave signal through the D/A converter 154. On the other hand, the amplitude of the voltage command is detected by 156 and multiplied])

The output of the D/A converter 154 is attenuated by a predetermined number, for example, 1/6, by an attenuator 155. From the above, since the third harmonic voltage command v3 is formed, by adding the deviation to the fundamental wave voltage command v1 using an adder, it is possible to obtain a control signal with a high voltage utilization rate.

However, the oscillation frequency of the V/F converter 21 at this time is 3N times the inverter setting frequency f, and after dividing this by 3 by the frequency division counter 201, the oscillation frequency of the V/F converter 21 is
It is obtained by dividing the frequency by N. Similarly, for the third harmonic voltage command v3, the oscillation frequency of the V/F converter 21 is calculated by the counter 152.
The frequency is divided by N and a ROM table reference method is used (see ROM 202). This ROM 202 has the same role as the phase shifter 16 in FIG. 1 by setting the sine wave table to sin (θ+270°), and has the same role as the multiplier 17 in FIG. We are trying to fulfill our respective roles. Note that the phase relationship between vl and v3 can be set correctly by system resetting the branch unit. That is, in this embodiment, the area 20 within the chain line frame corresponds to the reference numeral 15 in FIG. 5B. Comparing the two, in Figure 2 the PLL circuit shown in Figure 5B has been deleted and an N divider circuit has been newly added, but in general, the N divider circuit is simpler in configuration and has a lower cost. Since the cost is obvious, the effects of the invention are also obvious.
