Definitions
- the invention relates to power electronics for a synchronous motor, in particular synchronous motor in permanent magnet or reluctance design, regardless of the number of poles and phases.
- Synchronous motors are used in a variety of technical applications, such as B. in the household appliance, automotive and tool industry. In many places, they have prevailed over traditionally used universal motors because they have considerable advantages over the universal motors in terms of noise development, service life, weight and volume and the simplification and standardization of their manufacturing process, and they are also less expensive to manufacture.
- the premagnetized rotor (permanent magnet or reluctance) is driven by a magnetic field generated in the stator windings in synchronism with the frequency of the driving current in the magnetic field thus generated.
- the object of the invention is to utilize this residual energy, which is currently not usable, cheaply.
- FIG. 1 shows a schematic representation of the circuit diagram of a first variant for transferring the residual energy
- FIG. 2 shows a schematic representation of the circuit diagram of a second variant for transferring the residual energy
- FIG. 3 shows a schematic representation of the circuit diagram of a third variant for transferring the residual energy
- Fig. 4 is a schematic representation of the circuit diagram of a fourth variant for transferring the residual energy.
- Fig. 1 shows a schematic representation of the circuit diagram of a power electronics for a two-pole synchronous motor.
- Two phase windings 2, 4 are alternately connected to a voltage source (not shown here) via a rectifier bridge, a so-called Graetz bridge 6, and switches SI and S2 connected.
- An intermediate circuit capacitor C2 is connected in parallel with the phase windings 2 and 4.
- the magnetic field energy stored in its inductance during the energization of one of the two phase windings 2, 4, i. H. the residual electrical energy which is not converted into kinetic energy during the energization is transferred by means of transformer coupling, in the present case by means of a yoke 8, when switching to the other phase winding in its inductance.
- transformer coupling in the present case by means of a yoke 8
- a large part of the residual energy that cannot be converted into kinetic energy is shifted recuperatively from one phase winding 2, 4 and back again.
- FIG. 2 shows a schematic representation of the circuit diagram of a second variant that is alternative to the variant according to FIG. 1 or that can be combined with this.
- a design-related and / or a control-related dead time when an energized inductance, ie one of the two phase windings 2, 4 is switched off, an overvoltage is brought about in the switches SI and S2.
- These switches can be designed, for example, as IGBTs, MOSFETs or bipolar transistors.
- the overvoltage that occurs is transferred via the diode D1 or D2 into an RC relief network Rl, Cl that is used for both switches SI, S2.
- FIG. 3 shows a schematic representation of the circuit diagram of a third variant.
- This variant which has less loss than the second variant, shows two demagnetizing windings 10, 12 which are strictly coupled to the phase windings 2, 4. These demagnetization windings 10, 12 transfer the Residual energy not converted as kinetic energy back into the intermediate circuit capacitor C2 by means of transformer coupling.
- the diodes D3, D4 are only conductive during the demagnetization phase, which prevents an undesired (loss) energy flow through the
- Demagnetization phase 10, 12 occurs during the energization phase of phase windings 2, 4.
- Fig. 4 shows the circuit diagram of a fourth variant, which is particularly preferred when operating the engine with comparatively large powers.
- this circuit diagram is supplemented by two further circuit breakers S3, S4 and four demagnetizing diodes D5 to D6.
- These additional circuit elements act as two asymmetrical half bridges each associated with one of the two phase windings 2, 4. Through the use of these two half bridges, the entire residual energy, which has not been converted into kinetic energy and which is stored in the phase winding 2, 4 that is no longer energized, is fed back into the input capacitor C2, also called the intermediate circuit capacitor, and is thus available to the other, currently energized phase winding 2 or 4 are available.
- the power electronics can also be upgraded in such a way that a speed change is caused by targeted blanking of certain current supply sequences is made possible.
- a control unit not shown here, as a discrete, hardware-based solution or a program run as a software-based solution in a microcontroller, fades out the percentage of current supply sequences requested at the control unit.
- An energization sequence consists of the successive energization of the two phase windings 2, 4. For example, every tenth energization sequence is hidden for a required output of 90% of the total output. This can be accomplished, for example, by appropriate control of the switches SI and S2 designed as semiconductor valves.
- the torque of the synchronous motor is reduced. This has the effect that the speed changes due to the applied load in accordance with the specific torque-speed characteristic.
- Another advantage of the fourth variant is that, as an alternative, speed control is made possible by pulse width modulation of a transistor of the transistor pair that is energized relative to the motor frequency.
- the PWM current is freewheeling via one of the two freewheeling diodes in the branch that is energized.
- the effective current in the energized phase winding is reduced by the PWM and thus the energy supplied to the synchronous motor. A speed change thus takes place in the same way as in the first procedure described above.
- the design of a necessary duty cycle can be effected by using a microcontroller.
- a sensor can be provided as a Hall probe or optically or mechanically.
- the position detection starts the energization sequence for the phase windings 2, 4 depending on the rotor position determined. Due to the design properties, the time spans between the time of energization and the cheapest stator-rotor position, which runs into the energization, for starting and the preferred operating point at high speed differently.
- the microcontroller adjusts this time difference between the stator-rotor position and the time of energization according to an engine-specific operating point table according to the actual speed.
- a table can be stored as a map or as a speed-dependent functional relationship, for example as a rational function, in a memory element integrated in the microcontroller.
- the control unit e.g. B. the microcontroller and the entire power section, can also be arranged together as a hybrid circuit on aluminum substrate or film, but can also be mounted as a hybrid in a housing.
