Ein- und mehrphasige Umrichter mit der Möglichkeit zur Erhöhung der SpannungSingle and multi-phase inverters with the possibility to increase the voltage
Die Erfindung betrifft Umrichter, bestehend aus n (n ist größer oder gleich zwei) bidirektionalen Halbbrücken (HBi), mit jeweils einer positiven (HHi), mittleren (HMi) und einer negativen (HLi) Klemme, bestehend jeweils aus einem ersten aktiven Schalter (Sli), in Serie geschaltet mit jeweils einem zweiten aktiven Schalter (S2i), wobei zu jedem aktiven Schalter (Sli, S2i) eine antiparallele Diode (Dli, D2i) geschaltet ist, oder bestehend aus n (n ist größer oder gleich zwei) ersten aktiven Schaltern (Sli) mit jeweils antiparalleler erster Diode (Dli), n zweiten aktiven Schaltern (S2i) mit jeweils antiparalleler zweiter Diode (D2i), weiters bestehend aus n Spulen (Li) aus n Kondensatoren (Ci), einer ersten positiven (P) und einer zweiten negativen (N) Gleichspannungsklemme zum Anschluss einer unipolaren Spannungsquelle (Ul) oder einem Verbraucher und n Wechselspannungsklemmen (Wi) zum Anschluss der Last oder zur Anschaltung eines ein- oder mehrphasigen Netzes.The invention relates to inverters consisting of n (n is greater than or equal to two) bidirectional half-bridges (HBi), each having a positive (HHi), middle (HMi) and a negative (HLi) terminal, each consisting of a first active switch ( Sli), connected in series with a respective second active switch (S2i), wherein an antiparallel diode (Dli, D2i) is connected to each active switch (Sli, S2i), or consisting of n (n is greater than or equal to two) first active switches (Sli) each having antiparallel first diode (Dli), n second active switches (S2i) each having antiparallel second diode (D2i), further consisting of n coils (Li) of n capacitors (Ci), a first positive (P ) and a second negative (N) DC terminal for connection of a unipolar voltage source (Ul) or a consumer and n AC voltage terminals (Wi) for connecting the load or for connecting a single- or multi-phase network.
Umrichter dienen einerseits zur Verwandlung von Gleichspannungen in Wechselspannungen (einphasige Wechselrichter) oder in Mehrphasenspannungen (mehrphasige Wechselrichter), oder umgekehrt zur Umformung von einphasigen oder mehrphasigen Netzen in eine Gleichspannung (Gleichrichter). Im Folgenden sind die Schaltungen dreiphasig beschrieben und sind sowohl als Gleichrichter als auch als Wechselrichter geeignet. Als Lasten können synchron (Synchronmaschine, Schrittmotoren, geschaltete Reluktanzmaschinen) oder asynchron (Asynchronmaschine) funktionierende Maschinen, oder Netze verwendet werden. In zweiphasiger Anordnung kann damit ein einphasiges Netz erzeugt werden oder auch ein Vierquadrantenstellglied für einen DC Motor auf gebaut werden. Ebenso können die Schaltungen, wenn auf der Gleichspannungsseite z.B. ein Kondensator oder eine Gleichspannungsquelle geschaltet ist, als Blindleistungskompensator oder aktives Netzfilter verwendet werden.Inverters are used on the one hand for the conversion of DC voltages into AC voltages (single-phase inverters) or in polyphase voltages (polyphase inverters), or vice versa for the conversion of single-phase or multi-phase networks into a DC voltage (rectifier). In the following, the circuits are described in three phases and are suitable both as a rectifier and as an inverter. As loads synchronous (synchronous machine, stepper motors, switched reluctance machines) or asynchronous (asynchronous machine) functioning machines, or networks can be used. In two-phase arrangement so that a single-phase network can be generated or built a four-quadrant actuator for a DC motor. Similarly, if on the DC side, e.g. a capacitor or a DC voltage source is connected, be used as a reactive power compensator or active line filter.
Der klassische Umrichter besteht aus drei Halbbrücken, bestehend aus einer Serienschaltung von zwei aktiven Schaltern (in den Zeichnungen beispielhaft als MOSFETs gezeichnet, bei höheren Leistungen sind z.B. IGBTs, GTOs, IGCTs im Einsatz) mit jeweils einer antiparallelen Diode. Die Halbbrücken sind parallel geschaltet und mit der Gleichspannungsseite des Umrichters verbunden. Der Mittelpunkt jeder Halbbrücke bildet einen Anschluss der Wechselspannungsseite (Fig.l).The classical converter consists of three half bridges, consisting of a series circuit of two active switches (in the drawings by way of example drawn as MOSFETs, at higher powers are for example IGBTs, GTOs, IGCTs in use), each with an antiparallel diode. The half bridges are connected in parallel and connected to the DC side of the inverter. The center of each half-bridge forms a connection of the AC voltage side (Fig.l).
Bei den hier dargestellten Umrichtern werden teilweise ebenfalls Halbbrücken verwendet, doch werden diese anders zusammengeschaltet und zusätzlich kommen noch pro Halbbrücke ein Kondensator und eine Spule hinzu. In einer weiteren Schaltung wird das 1 P84/fh/20091027The inverters shown here also use half bridges in some cases, but these are interconnected differently and in addition, one capacitor and one coil are added per half bridge. In another circuit, the 1 P84 / fh / 20091027
Halbbrückenkonzept nicht verwendet, die aktiven Schalter und die ihnen antiparallel geschalteten Dioden sind als einzelne strombidirektionale Schalter in Verwendung. Durch die neuen Schaltungen entsteht eine größere Variationsbreite der Spannung an der Last.Half-bridge concept not used, the active switches and their anti-parallel connected diodes are used as single current bidirectional switches. The new circuits result in a greater variation in the voltage across the load.
Die Erfindung wird an Hand der Schaltbilder erläutert. Figur 1 eins stellt den klassischen Dreiphasenumrichter dar. Die Figuren Fig. 2 bis Fig. 4 stellen die neuen Umrichter, beispielhaft als dreiphasige Anordnungen und beispielhaft mit MOSFETs gezeichnet dar, natürlich ist aber jeder aktive Schalter, je nach Anwendung möglich.The invention will be explained with reference to the circuit diagrams. FIG. 1 shows the classic three-phase converter. FIGS. 2 to 4 illustrate the new converters, for example as three-phase arrangements and exemplarily with MOSFETs, but of course every active switch is possible depending on the application.
Die Aufgabe, einen Umformer für Gleichspannung in Wechselspannung oder mehrphasige Wechselspannung oder von Wechselspannung oder mehrphasiger Wechselspannung in Gleichspannung zu realisieren, wird erfindungsgemäß dadurch gelöst, dass die n Spulen (Li) einseitig miteinander und mit der ersten positiven Eingangsklemme (P) verbunden sind und der jeweils andere Anschluss jeder Spule (Li) an einen positiven Anschluss (HHi) einer Halbbrücke (HBi) geschaltet ist und alle mittleren (HMi) Klemmen der Halbbrücken (HBi) miteinander und mit der zweiten negativen Eingangsklemme (N) verbunden sind und jeweils an einer negativen (HLi) Klemme der Halbbrücken (HBi) jeweils eine Wechselspannungsklemme (Wi) geschaltet ist und zu jeder Halbbrücke (HBi) zwischen dem positiven Anschluss (HHi) und dem negativen Anschluss (HLi) ein Kondensator Ci geschaltet ist (Fig.2), oder dass die n Kondensatoren (Ci) einseitig miteinander und mit der ersten positiven Eingangsklemme (P) verbunden sind und der jeweils andere Anschluss jedes Kondensators (Ci) an je einen positiven Anschluss (HHi) einer Halbbrücke (HBi) geschaltet ist und ebenso die n Spulen (Li) einseitig miteinander und mit der ersten positiven Eingangsklemme (P) verbunden sind und die zweiten Anschlüsse der Spulen an je einer mittleren Klemme (HMi) einer Halbbrücke (HBi) geschaltet ist und alle negativen (HLi) Klemmen der Halbbrücken (HBi) miteinander und mit der zweiten negativen Eingangsklemme (N) verbunden sind und jeweils zu einer positiven (HHi) Klemme der Halbbrücken (HBi) jeweils eine Wechselspannungsklemme (Wi) geschaltet ist (Fig.3), oder dass die n ersten aktiven Schalter (Sli) mit antiparalleler Diode (Dli) kathodenseitig miteinander und mit der positiven Eingangsklemme (P) verbunden sind und jeweils anodenseitig ein Kondensator (Ci), dessen zweiter Anschluss mit der Anode einer zweiten Diode (D2i) und einer Wechselspannungsklemme (Wi) verbunden ist und eine Spule (Li) geschaltet ist, deren zweiter Anschluss mit der zugehörigen Kathode der zweiten Diode (D2i) und der zweiten negativen Gleichspannungsklemme (N) geschaltet ist (Fig. 4). 2 P84/fh/20091027The task of realizing a converter for DC voltage in AC voltage or polyphase AC voltage or AC voltage or polyphase AC voltage in DC voltage is inventively achieved in that the n coils (Li) are connected to one another and to the first positive input terminal (P) and the each other terminal of each coil (Li) is connected to a positive terminal (HHi) of a half-bridge (HBi) and all middle (HMi) terminals of the half-bridges (HBi) are connected to each other and to the second negative input terminal (N) and each at one negative (HLi) terminal of the half-bridges (HBi) is in each case connected to an AC voltage terminal (Wi) and to each half-bridge (HBi) between the positive terminal (HHi) and the negative terminal (HLi) a capacitor Ci is connected (Figure 2), or that the n capacitors (Ci) are connected on one side to each other and to the first positive input terminal (P) and the jewei ls other terminal of each capacitor (Ci) is connected to a respective positive terminal (HHi) of a half-bridge (HBi) and also the n coils (Li) are connected to one another and to the first positive input terminal (P) and the second terminals of the coils is connected to a respective middle terminal (HMi) of a half bridge (HBi) and all negative (HLi) terminals of the half bridges (HBi) are connected to each other and to the second negative input terminal (N) and each to a positive (HHi) terminal of the half bridges (HBi) in each case an AC voltage terminal (Wi) is connected (Figure 3), or that the n first active switch (Sli) are connected to the antiparallel diode (Dli) on the cathode side with each other and with the positive input terminal (P) and on the anode side, a capacitor (Ci) whose second terminal is connected to the anode of a second diode (D2i) and an AC terminal (Wi) and a coil (Li) is connected, the second terminal with the associated cathode of the second diode (D2i) and the second negative DC voltage terminal (N) is connected (Fig. 4). 2 P84 / fh / 20091027
Wenn die Schaltung durch Halbbrücken realisiert ist, ist es sinnvoll die Verschaltung der Halbbrücken durch Module zu bewerkstelligen. Weiters ist es sinnvoll zur Vermeidung von Überspannungen, verursacht durch parasitäre Induktivitäten zwischen der ersten positiven Klemme (P) und der zweiten negativen Klemme (N) ein oder mehrere Kondensatoren zu schalten und zwar möglichst nahe an die schaltenden Elemente.If the circuit is realized by half bridges, it makes sense to accomplish the interconnection of the half bridges by modules. Furthermore, it is useful to avoid overvoltages caused by parasitic inductances between the first positive terminal (P) and the second negative terminal (N) to switch one or more capacitors and as close as possible to the switching elements.
Die Einbindung der Konverterschaltungen in das Gesamtsystem, Die Ansteuerung der aktiven Schalter und die entsprechenden Steueralgorithmen können entsprechend dem Stand der Technik realisiert werden 3 P84/fh/20091027The integration of the converter circuits in the overall system, the control of the active switches and the corresponding control algorithms can be realized according to the prior art 3 P84 / fh / 20091027
