Definitions
- the invention relates to a polyphase DC-DC converter and a method for controlling a polyphase DC-DC converter.
- the current ripple reduces significantly in the superimposed output signal and the frequency of the output signal of the DC-DC converter increases by the number of offset clocked converter units relative to the basic clock frequency of the converter units. As a result, costs and volumes for output filters of the DC-DC converter can be reduced.
- the currents must usually be uniform or Be divided "symmetrically" to the individual converter units or phase modules.
- the present invention provides a multiphase DC-DC converter with at least two parallel, time-shifted coils, at least one control unit for driving the coils and at least one magnetic field-sensitive sensor element for detecting a magnetic field generated by the current flow through the coils, wherein the control unit controls the current flow through the coils in Dependence on an output signal of the at least one sensor element controls.
- the magnetic field-sensitive sensor element can be designed, for example, as a Hall sensor or as a magnetoresistive sensor or as a measuring coil.
- a magnetic feedback is realized by the detection and evaluation of the magnetic field generated in the coils, which can be used to compensate for load fluctuations or in the case of using a magnetic core to avoid saturation of the magnetic core, so that a regulated output signal is generated.
- asymmetries in the control or the structure of the polyphase DC-DC converter can be compensated.
- the at least two coils are magnetically counter-coupled, that is to say arranged and driven such that the magnetic fields generated by current flows through the coupled coils are directed in opposite directions.
- the coupling of the coils can take place, for example, via a common magnetic core, on which the coils are arranged.
- the magnetic core has an air gap.
- constant magnetic field components are almost completely eliminated and thus also prevents possible saturation of the magnetic core. This allows the use of smaller coils and magnetic cores and thus leads to smaller designs. If, despite the symmetrical structure, for example due to component tolerances or environmental influences, constant magnetic field components nevertheless result, they can be detected by the magnetic field-sensitive sensor and compensated by suitable control of the coils by the control unit.
- At least one magnetic field-sensitive sensor element is arranged in the vicinity of the air gap of the magnetic core.
- a magnetic flux leakage can be detected, which allows a conclusion on the magnetic field in the magnetic core and thus the stored amount of energy.
- the coils can then be controlled by the control unit in a suitable manner.
- the output signal of the sensor element can be evaluated integrally over time and thereby an offset value can be determined. This offset value provides a measure of a constant magnetic flux.
- the controller can then control the current flow through the coils to minimize this offset value.
- a sensor element can also be positioned in the air gap.
- the position is advantageously selected such that, with optimum symmetrical control of the coils, an output signal results without any offset.
- the sensor element detects a sum signal, that is, a signal which is based on the magnetic fields generated by a plurality of coils
- a sum signal that is, a signal which is based on the magnetic fields generated by a plurality of coils
- the sensor elements each deliver an output signal which generates a signal which is generated by the current flow through the respective coil. characterized magnetic field.
- the magnetic fields generated by the individual coils are evaluated so to speak separately in such a positioning of the sensor elements.
- separate evaluation and summation can also be combined in any way, that is, it can be both sensor elements are provided which detect individual magnetic fields, as well as other sensor elements which detect sum magnetic fields.
- the at least one magnetic field-sensitive sensor element is integrated into a control circuit of the polyphase DC-DC converter.
- the control circuit also comprises at least the control unit, but may also comprise further units, such as evaluation units for the output signals of the sensor elements.
- the control circuit also comprises at least the control unit, but may also comprise further units, such as evaluation units for the output signals of the sensor elements.

- Fig. 4 is a schematic side view of a first embodiment of a printed circuit with a polyphase DC-DC converter according to the invention.
- Fig. 5 is a schematic side view of a second embodiment of a printed circuit with a polyphase DC-DC converter according to the invention.
- FIG. 1 shows schematically and greatly simplified the structure of a polyphase DC-DC converter according to the invention.
- a magnetic core 1 which has an air gap 2
- two coils 3 and 4 are arranged in parallel, which are each part of a converter unit or a phase module of the polyphase DC-DC converter.
- the magnetic core 1 per se, the position of the air gap 2 and the arrangement and position of the coils 3 and 4 is advantageously carried out symmetrically.
- the arrangement of the coils 3 and 4 on a common magnetic core has a magnetic coupling of the two coils result.
- the coils 3 and 4 are each connected to an output stage 5 and 6, which comprise switching elements, not shown, for blocking or enabling a current flow through the coils 3 and 4.
- the output stages 5 and 6 are connected to a control unit 7, which controls the output stages 5 and 6 and thus the current flow through the coils 3 and 4 with a time offset or out of phase.
- the arrangement and control of the coils 3 and 4 is carried out such that there is a negative feedback between the coils 3 and 4, that is, the two coils generate magnetic fields with opposite orientation. With optimal symmetry of the arrangement and the control of the negative feedback all constant magnetic field components are eliminated, so that the DC component or DC component of the resulting magnetic field is zero. Due to component tolerances or other environmental influences However, even with symmetrical design and symmetrical activation, constant DC components result whose elimination leads to an improved function of the multiphase DC-DC converter.
- a magnetic field-sensitive sensor element 8 for example in the form of a Hall sensor, a magnetoresistive sensor or a measuring coil, is arranged. Via an evaluation unit 9, the output signal of the sensor element 8 is transmitted to the control unit 7. In this way, a magnetic feedback is realized. If the magnetic field sensitive Liehe sensor element 8, as shown, arranged in the vicinity of the air gap 2 of the magnetic core 1, then a magnetic leakage flux is detected by the sensor element 8, which allows conclusions about the magnetic field within the magnetic core 1 and thus to the amount of energy stored therein , Alternatively, the sensor element 8 may also be arranged in the region of the air gap 2. The sensor element 8 then does not detect the leakage flux, but enters
- Output signal which directly characterizes the magnetic flux in the magnetic core 1.
- the output signal of the sensor element 8 can be viewed integrally over time by the evaluation unit 9 and from this an offset value of the output signal can be determined.
- This offset value represents a measure of an existing constant magnetic flux.
- the control unit 7 can then control the coils 3 and 4 via the output stages 5 and 6, respectively, so that the offset value is minimized.
- an asymmetry of the coils 3 and 4 can be compensated.
- control unit 7, the two output stages 5 and 6 and the evaluation unit 9 are shown as separate units. Of course, these units can also be completely or partially integrated into a higher-level unit. It is also conceivable to provide the control of the individual output stages 5 and 6 or the coils 3 and 4 separate control units.
- FIG. 1 shows by way of example a two-phase DC-DC converter. However, by providing additional coils with corresponding output stages and control units, this arrangement can easily be expanded by further converter units or phase modules. If appropriate, other magnetic field-sensitive sensor elements should then also be provided in order to detect the magnetic fields generated by the further coils to be able to.
- the representation of the coupled by means of a magnetic core 1 coils 3 and 4 is merely exemplary understood. Other embodiments of the magnetic core 1 are possible. By suitable arrangement of the coils, a magnetic coupling of the coils can be achieved even without the use of a magnetic core.

- the output stages 5 and 6 are shown as a common unit 23.
- the sensor element 8 is preferably arranged in an edge region of the control circuit 20.
- the control circuit 20 is then positioned with respect to the coils of the polyphase DC-DC converter such that the sensor element is at the desired position, e.g. comes to lie in the vicinity of the air gap 2 of the magnetic core 1.
- FIG. 3 shows an alternative embodiment of a control circuit 20 'of a multiphase DC-DC converter.
- This embodiment differs from the embodiment shown in FIG. 2 only in that a second magnetic field-sensitive sensor element 8 'with an associated second evaluation unit 9' is provided. It is of course also possible again, the output signals of the sensor elements 8 and 8 'deviating from the illustrated embodiment by a common evaluation to process.
- the provision of two sensor elements 8 and 8 ' allows for a two-phase DC-DC converter the separate evaluation of the magnetic fields generated by the current flow in the coils, in particular if the two sensor elements 8 and 8' within the control circuit
- control circuit 20 is spaced from each other.
- Such a configuration of the control circuit can consequently also be used for a DC-DC converter with uncoupled coils.
- the control circuits shown in FIGS. 2 and 3 apply
- circuit components shown can also be combined in any manner in higher-level units.
- further circuit components or units can be integrated in the control circuit.
- further magnetic field-sensitive sensor elements can be integrated into a control unit, so that the control circuit can also be used, for example, for DC-DC converters having more than two converter units or phase modules.
- FIG. 4 shows a schematic side view of a first embodiment of a printed circuit with a multiphase device according to the invention.

- the magnetic field-sensitive sensor element, not shown, is then placed in a suitable position, e.g. positioned near an air gap 44 of the magnetic core 43.
