Embodiment Construction

[0087] exist figure 1 An example of a motor vehicle booster compressor 100 for a booster system of a heat engine is shown in .

[0088] as in figure 1 As shown in , the booster compressor 100 includes a rotary electric machine 200 and a turbine 300 coupled with the rotary electric machine 200 .

[0089] as in figure 1 As shown in , the rotating electric machine 200 comprises an electric motor 52 , the phases of which are connected to a power electronics card 54 , for example via connection means 240 . All these elements may be arranged inside the housing 50 closed by the cover 270 .

[0090] As already stated in the introduction, it is not feasible to solder electronic components (with their pins through the insulated metal substrate) directly from above on the insulated metal substrate in the same way as they are soldered to FR4 type epoxy printed circuits of.

[0091] figure 2 A pin 44 of a through-member placed at the rear face of the insulating metal substrate 11 is...

Abstract

The invention relates to an electric supercharging compressor comprising: a rotary electric motor (52) for driving the compressor; a power supply device for supplying power to the rotary electric motor (52); the electric motor (52) is one of a variable reluctance electric motor or a motor having a rotor provided with permanent magnets; the power supply device includes at least two electronic components (30) arranged at least partially around the electric motor (52) and spaced apart from one another at an angle of at least 5 degrees, in particular at least 10 degrees, preferably at least 20 degrees.

Description

technical field [0001] The invention relates to a power supply device for an electric booster compressor. Background technique [0002] Environmental concerns, especially to combat climate warming by reducing CO2 emissions, have prompted equipment manufacturers to offer motor vehicle manufacturers an electric booster compressor that improves The dynamic response of the internal combustion engine at low speeds. [0003] Unlike conventional superchargers driven by exhaust gas, the electric booster compressor (ie, driven by an electric motor) has instant response time, improving torque at low rpm and under acceleration. [0004] This system allows to significantly reduce the cylinder displacement volume of the heat engine and thus reduce the fuel consumption. [0005] Cylinders In the case of diesel engines, the reaction time of the gas booster compressor is responsible for the emission of particles during the acceleration phase at low rpm, when the injection system tries to ...
