Definitions
- the present invention relates to a PWM cyclo-converter that realizes an arbitrary current waveform by using a PWM converter connected to an input unit of a PWM cyclo-converter and suppresses input current distortion.
- Fig. 6 shows a conventional PWM cycloconverter system.
- 1 is a three-phase AC power supply
- 2 is a three-phase AC rear turtle
- 3 is a three-phase AC capacitor
- 4 is a bidirectional switch group
- 5 is a load motor
- 6 is a three-phase AC rear turtle
- 7 is AC to DC.
- PWM converter for converting 14 is a smoothing capacitor which is a DC voltage means, 9 is a detection current signal of a three-phase AC power supply, 10 is a current detection CT which is a current detection means for detecting a current of the three-phase AC power supply, 11 Is a CT for current detection as current detection means, 12 is a detected current signal of the CT for current detection, and 15 is a snubber circuit provided in each bidirectional switch of the bidirectional switch group 4.
- FIG. 6 shows a conventional example in which the resonance voltage of the input filter is suppressed by a small-sized PWM converter as in the present invention.
- the output of the PWM converter is connected to the subsequent stage (secondary side) of the filter to suppress the voltage, if a current more than the amount of the resonance component correction is passed, the fluctuation of the capacitor voltage will increase, The disadvantage was that the amount of correction was limited. Therefore, the effect is particularly limited in the method shown in Fig. 3 that regenerates the energy of the snapper.
- a PWM cycloconverter is an AC-AC direct power converter that directly converts a three-phase AC power supply voltage into a variable voltage (arbitrary voltage and frequency) with a variable frequency.
- a north-like current flows through the input portion of the power semiconductor device.
- a low-pass filter is generally provided using an AC reactor and an AC capacitor.
- a resonance phenomenon occurs between the rear turtle and the capacitor, and a resonance current flows through the input section. Due to the resonance current, the distortion rate of the input current is degraded.
- the PWM cycle converter is not operating, the current flows to the capacitor and the resonance current A flow also occurs.
- the present invention has been made in view of such a problem, and an object of the present invention is to provide a PWM cyclo-converter device capable of improving an input current waveform and easily regenerating a snapper energy power supply.
- the present invention provides a PWM cycloconverter, which has a PWM converter device connected to a DC voltage system, and an output unit of the PWM converter device is provided at a stage preceding the input filter (primary side) of the PWM cycloconverter. It is connected to regenerate snubber energy and improve input current by converter current.
- the PWM cycloconverter is connected to an input terminal of a power semiconductor element.
- One or more voltage clamp devices having a diode rectifier and a smoothing capacitor, and a voltage detecting device for detecting a voltage between both ends of the smoothing capacitor, wherein the voltage clamping capacitor is used in place of the DC voltage means. It is.
- a snubber device composed of a diode and a capacitor connected to the input / output terminal of the power semiconductor element of the PWM cycloconverter, and a snubber voltage detector for detecting a voltage across the smoothing capacitor connected to the snubber device.
- a device for using the snubber capacitor as a substitute for the DC voltage means is also provided.
- the PWM cycloconverter can control the input current waveform due to its principle. However, since it is directly connected to the output section by a bidirectional semiconductor switch, the output current must be controlled at the same time. As a result, the input current control performance is restricted.
- the present invention relates to an auxiliary device for improving the control performance of such a PWM cycloconverter, and easily realizes input current control by diverting a general and small-sized PWM converter.
- FIG. 1 shows a system configuration for implementing the present invention using a PWM cycloconverter and a PWM converter using a DC voltage source.
- FIG. 2 shows a system configuration using a PWM converter that uses a PWM cycloconverter and a diode rectifier circuit to implement the present invention.
- FIG. 3 shows a system configuration of a PWM converter using a DC voltage source created by a PWM cycloconverter and a snubber circuit for implementing the present invention.
- FIG. 4 shows an example of a snubber circuit configuration diagram for implementing the present invention.
- FIG. 5 shows an example of a snubber circuit configuration diagram for implementing the present invention.
- FIG. 6 shows an example of a system configuration of a conventional PWM cycloconverter and an example of a filter resonance suppression method.
- the PWM cycloconverter is directly connected between the three-phase AC power supply 1 and the three-phase output, which is the input current of the motor 5, using a total of nine bidirectional semiconductor switch groups 4 to reduce the AC power supply voltage. Any frequency and voltage can be output without converting to DC. However, a pulse-like current flows through the input stage of the bidirectional semiconductor switch group 4.
- an input filter is configured using a three-phase AC reactor 2 and a three-phase AC capacitor 3.
- the present invention provides an input filter as described above by providing a DC power supply 8 separately from the AC power supply 1, providing a small PWM converter 7 therein, and supplying a current to the front stage of the input filter of the PWM cyclo converter. Can suppress the resonance current.
- the input current signal 9 detected by using the current detecting CT 10 is input to the control unit of the PWM converter 7, and is compared with an arbitrary current waveform realized by the PWM cycloconverter, and the correction is performed. By supplying the same current, the ideal input current waveform is realized. Further, by detecting the correction current signal 12, the control performance thereof can be improved.
- the correction method if the control target is only the resonance current among the harmonic components of the input current, the input current signal 9 is compared with the ideal sine wave, and if the correction current is passed from the PWM Suppression can be realized. In this case, the resonance current depends on the filter design, but its current value is sufficiently small compared to the entire input current. Therefore, the current capacity of the PWM converter 7 can be small, and the cost is small.
- FIGS. 4 and 5 show the circuit configuration of the snapper circuit 14 in FIG. 3, and configurations such as the snubber diode group 15 and the snubber diode group 16 are conceivable.
- the snubber circuit 14 as the DC power supply voltage of the PWM converter 7 of the present invention, it is possible to use the snubber circuit 14 as a correction current without wasting energy due to a surge generated at the time of switching, thereby achieving higher efficiency in the entire system. it can.
- the present invention can improve the input current waveform and easily regenerate the power of the energy of the snapper, so that the electric motor can be driven with energy saving, and the electric vehicle, the elevator, and the crane can be used to regenerate the power without consuming power as heat. It is particularly useful as a control device for a motor such as a winding machine.
