Description of the invention (1) [Industry use field] The present invention relates to the main power conversion device such as a converter device using its own arc-extinguishing switching element Improver of circuit configuration. [Prior Art] Previously, the configuration of the vibration-damping circuit of the self-arc-extinguishing switching element installed in a relatively large converter device was disclosed in, for example, ① Shikai Zhao 5 9-1 4 9 4 8 9 Gazette , ② Shikai Zhao 6 1 — 1 5 6 4 9 0 bulletin, ③ Shikai Zhao 6 2 — 4 1 3 8 9 bulletin, ④ Special Open Zhao 6 2_2 1 7 8 6 4 bulletin, and ⑤ Special Kaiping 5 — 2 8 4 7 3 No. 1, etc. That is, it is provided in parallel with the switching element, and in series with the capacitor and the diode, and a resistor is connected between the connection point of the capacitor and the diode and the DC terminal on the opposite side. Through this, the impact energy at the time of switching off of the switching element is absorbed by the above-mentioned capacitor, and the absorbed impact energy is dissipated through the above-mentioned resistance, so-called polarity damping circuit. [Problems to be Solved by the Invention] In the above-mentioned prior art, since the impact energy generated when the switching element is turned off, it is necessary that all of the energy is absorbed by the capacitor in the polarized vibration damping circuit. In addition, the m-capacitance that consumes its absorbed energy also becomes large. The purpose of the present invention is to reduce the vibration damping accommodation and realize a simplified commutation and other force conversion device, or a vibration damping device thereof.

Description of the invention (2) [Method for solving the problem] On one hand, the invention has: An inverter connected to a DC power supply, having its own arc-extinguishing switching element in each phase positive and negative arms, which converts DC power into variable voltage and variable frequency AC power, and includes self-arc arc extinguishing with the above arms -Shaped switching element connected in parallel with the first capacitor and diode connected in series with polar dampers, and the resistor connected between the series connection point of these first capacitors and diodes and the DC power line on the opposite side The converter device is characterized in that, between the positive and negative ends of the DC power supply, a second capacitor is connected in parallel across the series of positive and negative arms of each phase, respectively. Another aspect of the present invention is to integrate the first capacitor and diode series body and one phase portion of the second capacitor in one unit. (Please read the precautions on the back before filling out this page) Printed by the Dingbu Bureau of the Ministry of Economic Affairs Employee Consumer Cooperative [Function] When the second capacitor is added to the above polar damper, when the switching element is off The impact energy generated is absorbed by the first and second capacitors, which can reduce the above-mentioned polar damping capacity. In this case, the capacity is increased by only increasing the number of parallel connection of the first capacitor, which is divided into the first and the first. The second m container is connected, and the arranger can shorten the wiring distance from the switching element to the capacitor, which can effectively reduce the capacity of each element of the vibration reduction circuit, and can be small and light. In addition, when the first capacitor and diode and the second capacitor in the above vibration reduction circuit are stored in a single module and modularized, the paper standard is applied to the Chinese National Standard (CNS) A4 specification (210X 2W Cli) -5 _ 205743 A7 B7 Printed by the Employee Consumer Cooperative of the Central Standard Falcon Bureau of the Ministry of Economy V. Invention description (3) The wiring distance between the switching element and the vibration-damping circuit element is the shortest, which can make the accommodation of the vibration-damping circuit element more For effective reduction. [Embodiment] FIG. 1 is a configuration diagram of a commutation main circuit according to an embodiment of the present invention. 0 DC power is supplied from a DC source 1, 2 through a smoothing capacitor 3 to an inverter 4. Inverter 4 converts this DC power into AC power of variable voltage and variable frequency (VVVF), and supplies power to 3-phase induction motor 5. The induction motor 5 rotates the pulley 7 via the speed changer 6 to drive the elevator boarding box 8 and the counterweight 9 up and down. The inverter 4 forms a three-phase positive and negative arm through its own arc-extinguishing switching element, such as I GBT 1 0 1 ~ 1 0 6. These IGBTs are controlled by PWM through the gate signal generating circuit 11. In the self-arc-extinguishing switching element, there must be a shock absorber that absorbs the energy of its arc-extinguishing (off). First of all, it is well-known that it is connected in parallel with each element 10 1 ~ 1 0 6 and a series body of a capacitor 2 0 1 ~ 2 0 6 and a diode 3 0 1 ~ 3 0 6 is connected. Furthermore, through the resistors 4 0 1 to 4 0 6, the series connection points of these series bodies are connected to the DC power supply line N or P on the opposite side. Furthermore, in this embodiment of the present invention, between the positive and negative lines P and N of the DC power supply, there is a series of positive and negative arms across the phases, and a second capacitor 5 for each phase connected in parallel with each 0 1 ~ 5 0 3 〇The standard of this paper is the Chinese National Standard (CNS) Λ4 specification (2 丨 Ox2 <? 7 praises) _ nf n ^ — ^^^^ 1 ^^^^ 1 —Bm ^^^^ 1 TJ.,, \ Bing (please read the precautions on the back before filling this page) A7 B7 Printing and Burning of the Consumer Labor Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs V. Invention description (4) Next, take the U phase as an example to explain vibration reduction The role of the device. Now, when the switching element 10 1 is ON and the switching element 10 2 is OFF, consider the case where the switching element 10 1 is OFF. The current flowing through the switching element 101 is quickly interrupted, and a surge voltage is generated across the switching element 101. In this way, the same voltage is applied to the series connection of the capacitor 201 and the diode 300, the diode 300 turns on immediately, and the above-mentioned impact energy is absorbed by the capacitor 201. That is, the capacitor 201 charges in the direction + in the figure. The energy absorbed in this way is then passed through the capacitor 2 0 1 (+) —DC line P— IGBT1 0 1—AC line U —induction motor 5 —AC line V—1GBT10 4 (or AC) when the switching element 101 is turned ON again.

Similarly, in the state where the switching element 101 is OFF and 102 ON, when the switching element 10 2 is OFF, the current flowing through the switching element 102 is quickly interrupted, and a surge voltage is generated across the switching element 102. In this way, the same voltage is applied to the series body of the capacitor 2 0 2 and the diode 3 0 2, and the diode 3 0 2 is turned on immediately. The above-mentioned impact energy is absorbed by the capacitor 2 0 2. That is, the capacitor 202 is charged in one direction toward the tenth shown.
