In power switched semiconductor, pass through typically unusual feelings of the ceramic insulation portion of thin-walled in the power semiconductor Under condition by the interference voltage coupling input of high frequency into the cooling body.Similar interference is also in the power to radiate via cooling body It is transmitted in choke valve in the cooling body.

Required heat of the interference due to high switch speed and towards the cooling body direction, which is drawn, to be unable to Directly influenced.

Therefore, as counter-measure usually by the access of Cy capacitor between the intermediate loop and the cooling body, institute State Cy capacitor be responsible for making at least part thus caused by interference electric current directly return and direct into the intermediate loop.

If the cooling physical efficiency is touched from outside, must be by the cooling body for example corresponding to according to EN's 61140 Protection class I and PE(Protective Earth, protective grounding) connection.However, via this low ohm company for leading to PE Socket part, a part of interference electric current flow away into the supply power grid and thus not only in wired EMV measurements but also in quilt It is visible in the EMV measurement of transmitting.

In order to abide by the EMV standard, it is necessary to increase the Cy capacitor, however this improves the ground line current.It is described Combination failure electric current-protective switch (F- switch) causes problem again for the raising of ground line current.

If be grounded at inverter output end in IT- power grid, the Cy capacitor by high heat load simultaneously And it being capable of failure.Failure must be installed into IT- separated part in order to prevent, and the Cy capacitor is made at the IT- separated part It is separated with the PE potential.Many application persons have excessive demand for this problem, this brings additional support to expend.

According to the present invention, the cooling body be so integrated into it is described control instrument shell in so that the cooling body from Outside can no longer be touched, thus the cooling body can also for example according in the instrument of the protection class I of EN 61140 with PE insulation.

Save the low ohm interconnecting piece for leading to PE as a result, and coupling input to the interference electric current in the cooling body not The control instrument can be left.The Cy capacitor can smaller determine size as a result, and the interference electric current is to institute The feedback stated in intermediate loop is obviously better worked.

In addition, being no longer able to that the thermal overload of the Cy capacitor occurs, because the Cy capacitor is not in IT- power grid It is connect again with PE.Thus, it is no longer necessary to disconnect PE- interconnecting piece.

According to the present invention, the electric insulation part of the cooling body can be with very small in the case where air cooled instrument Extra cost realizes that the extra cost is significantly less than the EMV interference protection measure additionally needed.Generally, thus, it is possible to It is enough to realize the control instrument for having following power electric device, compared with when the cooling body be with PE connection, the power Electronic device obviously can manufacture to more cost-effective for the EMV that can be compareed is required.

According to the present invention, the cooling body is encased in shell, such as plate shell, the shell receives the cooling Component (especially partly lead by choke valve and power for body and all fixations or (and being cooled down together) for screwing at the cooling body Body) mechanical power and weight, and further direct into the fixed point of the shell, for example further direct into it is described At the back wall of shell.

Here, two plastic components can undertake the function of electric insulation part, mode is that described two plastic components pass through The cooling body is mechanically fixed against the interconnecting piece without guide function (such as via metal threaded by the interconnecting piece of shape cooperation Fastener) it is connected across the insulation division.

It is whole as described above in a similar way by interference voltage coupling input into the cooling body The hot link at the cooling body of coil or choke valve support the EMV behavior as follows so that the interference is also with small Consuming be retained in the instrument and can be routed back in the intermediate loop.

It ideally arranges and the Cy capacitor for being properly determined size reduces interference voltage in the cooling body, side Formula is to return to the energy for being coupled input in the intermediate loop with thus low inductance interconnecting piece guidance via short.

In order to avoid arriving the subsequent EMV at the output section for example in power grid feedback unit form of the control instrument Capacitive couplings at filter construct the EMV filter and the cooling body discretely and only via in the instrument The air that recycles in device cools down.This wasted power that may be significantly smaller due to the EMV filter and can simply implement. Pass through the separating and avoid the condenser type interfered in the supply lines (DC and AC) spatially of the EMV filter Coupling input.
