Definitions
- the invention relates to a converter according to the preamble of the main claim. This is preferably a DC-AC converter.
- the intermediate voltage circuit can also be formed by a direct voltage network, which contains, for example, the on-board electrical system battery of a motor vehicle.
- the voltage intermediate circuit also has an intermediate circuit capacitor, using which pulse currents are generated or the alternating current is taken over. Such pulse currents occur in all clocked converter bridges.
- a Umrichtexmaschine consists of one or more half bridges, which alternately connect the output to either the positive or the negative DC link potential.
- a half bridge has one or more high-side switches for the connection to the positive intermediate circuit potential and one or more low-side switches for the connection to the negative DC link potential.
- a high-side switch and a low-side switch together form a half bridge.
- the DC voltage converter on the electrical system side is designed as a bidirectional converter, in order to be able to transfer electrical energy from the on-board electrical system battery to the DC link for the starting process or its preparation, and to transfer energy from the DC link to the low voltage side during generator operation of the starter motor, in order to transfer consumers there To feed the on-board electrical system and to charge the on-board electrical system battery.
- a converter according to the invention has the
- two or more capacitors which extend parallel to the complete half bridge, are integrated into the module per half bridge. This reduces the interference radiation from the converter bridge.
- FIG. 1 shows a representation of a half-bridge according to an exemplary embodiment for the invention
- FIG. 2 shows a simplified module representation of the half-bridge according to FIG. 1
- FIG. 3 shows an equivalent circuit diagram of the half-bridge module
- FIG. 4 shows a first exemplary embodiment for a converter
- FIG. 5 shows a second exemplary embodiment for a Converter
- Figure 6 shows a third embodiment of a converter, only the components necessary for understanding the invention are shown in the figures. description
- FIG. 1 shows an illustration of a half bridge according to an exemplary embodiment of the invention.
- the half bridge is realized in the form of a module M arranged in a housing.
- capacitors C H s, C LS , C K ⁇ and C ZK2 are also integrated in this module M.
- the capacitors C H s and C LS are each arranged in parallel with an inverse diode and a switch. They serve to mitigate the negative effects of the current stall behavior of the inverse diodes during the switching processes.
- a current stall means a very rapid change in current, which leads to corresponding overvoltages caused by the parasitic inductances.
- the two other capacitors C ZK ⁇ and C ZK 2 / which are each arranged parallel to the entire half bridge and thus directly on the
- DC link voltage are used as block capacitors for the DC link. At the same time, they are intended to filter out high-frequency current components, which leads to an improvement in electromagnetic compatibility (EMC). Furthermore, these two capacitors C ZK1 and C Z ⁇ 2 also take over the task of a conventional intermediate circuit capacitor in whole or in part.
- FIG. 2 shows a simplified schematic module representation of the half-bridge according to FIG. 1.
- the intermediate circuit capacitors C ZK ⁇ and C ZK2 are described by the capacitor C z ⁇ .
- an ohmic resistance R D is shown, which represents the internal resistance or damping resistance of the capacitor.
- the inductance L z ⁇ of the connection connection forms a resonant circuit together with the capacitor C 2 ⁇ .
- Half-bridge module This shows that the half-bridge module is a damped series resonant circuit11.
- the voltage U Ven tii at the semiconductor switches is composed of the capacitor voltage U c plus the voltage drop U R at the damping resistor nd R D.
- the voltage is the load current can be assumed to be constant.
- the starting values of the energy storage are therefore:
- the minimum capacitance value C z ⁇ is calculated , min ie follows: In the range of resonant vibrations up to the aperiodic limit case (0 ⁇ D ⁇ 1) the minimum capacitance value C z ⁇ , m i n is calculated as follows:
- the overvoltage in this area is only determined by the capacitor C z and not by the
- Damping resistance R D Low-damped capacitors cause vibrations between the inductors and the capacitors. With low damping, the resonant vibrations of two switching processes can overlap, which results in larger overvoltages. With large damping resistances (D>1; corresponds to the non-resonant case), the overvoltage depends on the ohmic voltage drops. As a favorable damping factor
- FIG. 5 shows a second exemplary embodiment of a converter.
- Several half bridges are also provided in this case, each of which is implemented as a module.
- the sum of the capacitance values of the capacitors C z ⁇ or C ZK ⁇ and C ZK2 integrated in the half-bridge modules is sufficient for the intermediate circuit , so that an additional, external intermediate circuit capacitor can be dispensed with. This can be the case in particular when the switching times are offset.
- a low-inductance connection via a busbar B is only provided between the half-bridge modules.
- the converter can be connected to the DC link via a conventional connecting line or via a busbar.
- the line inductance can also be used as a filter inductance or can also be used.
- FIG. 6 shows a third exemplary embodiment for a converter. With this, all partial bridges are part of a single module. This solution eliminates the need for a bus bar, since the half-bridges are interconnected with each other in a very low-inductance manner.
- the module can be connected to the DC link by means of a busbar.
- the inductance of this busbar can also be used as the inductance of an output filter.
- the invention divides a conventional intermediate circuit capacitor into several intermediate circuit capacitors of smaller capacitance, some or all of which are an integral part of a half-bridge or bridge module. This leads to a reduction in overvoltages that occur, an improvement in electromagnetic compatibility, high switching speeds with low switching losses in the semiconductor switches and a reduction or elimination of a busbar provided in the prior art.
