Definitions
- the invention relates to a DC / DC converter arrangement for the galvanically isolated, at least indirect, electrical coupling of a fuel cell unit to a traction network comprising a high-voltage battery.
- the DC voltage converter arrangement comprises a fuel cell-side electrical first connection pair, to which an input DC voltage is or can be applied, the DC input voltage being established by means of a first full switch bridge comprising a first switch and by means of a second full switch bridge comprising a second switch connected in parallel with the first full switch bridge an AC voltage is transformable.
- the AC voltage provided by the first full switch bridge can be transformed from a first primary side of a first transformer to a first secondary side of the first transformer in a predetermined or a predeterminable ratio.
- the AC voltage provided by the second full switch bridge can be transformed from a second primary side of a second transformer to a second secondary side of the second transformer in a predetermined or a predeterminable ratio.
- the transformed alternating voltage is by means of a fourth switch comprising a third switch electrically connected to the first secondary side of the first transformer and by means of a fourth switch comprising a fourth switch connected in series with the third switch bridge and electrically connected to the second secondary side of the second transformer
- Switch full bridge can be transformed to an output DC voltage, which is provided or can be provided on a battery-side electrical second connection pair.
- the invention further relates to a method for operating such a DC voltage circuit arrangement and a fuel cell vehicle.
- the requirements for insulation resistance according to ISO 6496-3 (in the version valid at the time of the priority of the present application) must be met.
- the insulation resistance is voltage-dependent and must therefore have higher values for larger voltages in order to protect against insulation faults.
- the fuel cell stack itself has a comparatively low insulation resistance, so that it fulfills requirements for a traction network in the range from 350 volts (V) to 450 V, in particular 400 V.
- V volts
- fuel cell vehicles with an 800 volt architecture in particular, run the risk of not meeting the requirements of ISO 6496-3.
- the DC / DC converter arrangement according to the invention is distinguished in particular by the fact that at least one of the full switch bridges is integrated in a resonant circuit comprising an inductor and a capacitor.
- the resonant circuit has the advantage that the load current flows sinusoidally through the switches, being shifted in the positive direction by the amount of the output current. There is therefore only a low probability that the switching operation of the switches takes place precisely when the amplitude of the load current is at a maximum, so that in at least a large number of switching operations the switches do not carry the full load current and are therefore thermally relieved.
- a particularly simple construction which at the same time leads to a compact design of the direct voltage converter arrangement, is characterized in that the resonant circuit is assigned to the secondary transformer on the secondary side and the resonant circuit by means of a leakage inductor provided on the secondary side - activity of the first transformer and / or the second transformer.
- the capacitor and / or the leakage inductance is dimensioned or designed such that a load current flowing through the third switches of the third full switch bridge and / or a load current flowing through the fourth switches of the fourth full switch bridge is reduced, in particular minimized.
- the switching times of the switches are selected such that they essentially correspond to the zero crossings of the essentially sinusoidal load current through the switches.
- a further thermal relief of the switches and thus an increase in efficiency can be achieved in that the first transformer is assigned a first resonance circuit, driven by means of leakage inductance on the secondary side and comprising a first capacitor, and that the second transformer is driven by leakage inductance on the secondary side , a second resonant circuit comprising a second capacitor is assigned.
- an output connection pair of a step-up converter electrically connected to the fuel cell unit is connected to the first electrical connection pair.
- the voltage provided by the fuel cell unit can be increased in a ratio of 1.2 to 1.5 times by means of the step-up converter, the DC input voltage UE being provided at the output of the step-up converter.
- the step-up converter has a first DC voltage position on the input side and a second DC voltage position which is higher than the first DC voltage position on the output side, the second DC voltage position corresponding to the input DC voltage and the output DC voltage again compared to the DC input voltage was increased.
- a more compact and more highly integrated fuel cell system can be formed by the fact that the DC / DC converter arrangement provides a distribution unit on the output connection pair of the step-up converter, which is electrically connected there.
- the distribution unit is preferably electrically connected on the output side to at least one secondary consumer of a fuel cell system comprising the fuel cell unit.
- Secondary consumers of the fuel cell system can be, for example, coolant pumps, recirculation fans, compressors and the like.
- an electrical resonant circuit comprising a capacitor by means of a leakage inductance of the first transformer and / or the second transformer on the secondary side, such that an essentially sinusoidal load current flowing through the switches of at least one of the full switch bridges is essentially at zero crossing at the switching instant.
- An integrated resonant resonant circuit is thus implemented which uses the leakage inductance of the first transformer and / or the second transformer to reduce the load current during the switching process through the switches and thus to thermally relieve the switches of the full switch bridges.
- the fuel cell unit provides a first DC voltage position which is picked up on the input side by a step-up converter which provides a second DC voltage position which is higher on the output side and if the second DC voltage position corresponds to the input DC voltage .
- FIG. 1 shows a schematic block diagram of a DC converter arrangement for the electrically isolated electrical coupling of a fuel cell unit to a traction network (vehicle electrical system), which provides a total of three different DC voltage layers
- FIG. 2 shows an equivalent circuit diagram of a DC converter arrangement for the electrically isolated, at least indirect, electrical coupling of one 3 shows the current profile, the voltage profile and the switching losses while the switches of a full switch bridge of the DC voltage converter arrangement from FIG. 2 are switched off,
- Figure 4 is an equivalent circuit diagram of a DC converter arrangement from the prior art
- FIG. 5 shows the current profile, the voltage profile and the switching losses when the switches of a full switch bridge of the DC-DC converter arrangement from FIG. 4 are switched off.
- FIG. 4 shows a DC voltage converter arrangement 100 according to the preamble of claim 1. Analogously to the DC voltage converter arrangement 100 according to the invention (FIG. 2), this is also designed to electrically couple, at least indirectly, a fuel cell unit 102 electrically, with a traction network 106 comprising a high-voltage battery 104.
- the DC voltage converter arrangements 100 have an electrical first connection pair 108a, 108b on the fuel cell side, to which an input DC voltage UE is present or can be applied.
- the DC input voltage UE is open by means of a first switch full bridge 1 10 comprising a first switch Sn, S12, S13, Si 4 and by means of a second switch bridge 1 12 comprising second switches S21, S22, S23, S24 connected in parallel to the first switch full bridge 1 10 an AC voltage can be transformed.
- the AC voltage provided by the first full switch bridge 110 can be transformed from a first primary side 114 of a first transformer Ti to a first secondary side 116 of the first transformer Ti in a predetermined or a predetermined ratio.
- the alternating voltage provided by the second full switch bridge 112 can be transformed from a second primary side 118 of a second transformer T2 to a second secondary side 120 of the second transformer T2 in a predetermined or a predeterminable ratio.
- the transformed AC voltage is connected to the second secondary side 120 by means of a third full switch bridge 122 comprising third switches S31, S32, S33, S34, which is electrically connected to the first secondary side 116 of the first transformer Ti, and by means of a third full side bridge 122 connected in series with the third full switch bridge 122 of the second transformer T2 electrically connected, fourth switch S 4i , S 4 2, S 4 3, S 44 , fourth full switch bridge 124 transformable to an output DC voltage UA.
- the DC output voltage UA is provided or can be provided on a battery-side electrical second connection pair 126a, 126b and is preferably at the voltage level of a high-voltage battery 104, in particular a voltage level of an 800V architecture.
- FIG. 5 shows the metrological examination of a switch-off process of the third full switch bridge 122 and / or the fourth full switch bridge 124 in the DC converter arrangement 100 of the prior art.
- the first transformer Ti is assigned a first resonant circuit 128, which is formed by means of a leakage inductance Lsi of the first transformer Ti and a first capacitor CRI.
- the second transformer T2 is assigned a second resonant circuit 130, which is formed by means of a leakage inductance Lsi of the second transformer T2 and a second capacitor C R 2.
- the capacitors CRI, CR2 and the leakage inductances Lsi, Ls2 are dimensioned or designed such that one through the third switches S31, S32, S33, S34 of the third full switch bridge 122 and one through the fourth switches S 4i , S 4 2, S 4 3 , S 44 of the fourth full switch bridge 124 flowing load current is reduced, in particular minimized.
- the switching times of the switches S31, S32, S33, S34; S41, S42, S43, S44 selected such that they essentially the zero crossings of the sinusoidal load current through the switches S31, S32, S33, S34; S41, S42, S43, S44 correspond.
- the first voltage level is generated by the fuel cell unit 102, which is in the range from 200V to 300V.
- This first DC voltage position is provided on the input side at the step-up converter 134, which increases the voltage to a second DC voltage position, which corresponds to the DC input voltage U E.
- the DC input voltage UE can be used to electrically supply auxiliary consumers 138 of a fuel cell system comprising the fuel cell unit 102, a voltage level being present here in particular, which lies in a range from 350V to 450V.
- FIG. 1 also shows the possibility of using fuses 140.
- the DC input voltage UE can also be used to connect the traction network 106 comprising the high-voltage battery 104, here being galvanically isolated in order to meet the requirements for the insulation resistance in accordance with ISO 6496-3.
- This tract Onsnetz 106 is operated at a voltage level of 800V, for example, so that the third voltage level is thus realized.
