Definitions
- the invention relates to an electronic drive control according to the preamble of claim 1.
- An electronic drive control for a magnetic drive with pulse width modulation of the armature current is known from EP 0 789 378 A1.
- the armature coil is operated with a constant voltage.
- the frequency of a pulse width modulator (PWM) or the T on time cannot be chosen arbitrarily. Due to the development of noise in the magnetic circuit due to the pulsing of the drive coil, in contrast to the pull-in control, in which this brief noise development is completely covered by the movement process of the entire drive, it is necessary to set the PWM frequency for the holding operation to a frequency which is outside the human Listening area. Frequencies outside the human hearing range are above 20 kHz. This corresponds to a period of 50 ⁇ s. The required current reduction to the holding mode would result in a relatively short T on time of, for example, 400 ns, taking into account control reserves and other factors.
- PWM pulse width modulator
- the object of the invention is therefore to provide an electronic drive control according to the preamble of claim 1, with which the holding operation can be implemented with as little noise and noise as possible over a large voltage range.
- the holding pulses can be finely graduated accordingly by the invention.
- the holding power is minimized in a simple manner.
- Fig. 1 is an illustration of the drive coil with semiconductor switches for suit and
- Fig. 3 is an illustration of the pulse shaper stage
- Fig. 4 is a pulse and voltage diagram.
- FIG. 1 shows the drive coil 1 of a contactor with a freewheeling diode 2, with a semiconductor switch 3 for the holding mode, a further semiconductor switch 4 for the suit and the pulse shaper stage 5, which is connected upstream of the control input of the semiconductor element 3.
- the temperature is already taken into account on the analog side of the voltage measurement, in that the gain factor of an operational amplifier is influenced by a temperature-dependent resistance in such a way that the measured input voltage is multiplied by the reciprocal of the correction factor k ⁇ .
- the PWM determination is carried out by means of a map control, which is shown in FIG. 2. With this control, the PWM values are calculated in advance, taking into account all determinable, constant correction factors, and are stored as a fixed correction table in a data memory 8 of a microcontroller.
- the clock ratio of the PWM modulator 9 is not arbitrary, but rather can only be set as an integral multiple of the clock frequency or a variable derived therefrom.
- the microcontroller is operated with an oscillator of 10 MHz.
- the oscillator frequency is reduced internally again by a divider 10/1 to a clock frequency of 1 MHz, so that a minimum of 1 ⁇ s can be set as the shortest T 0N time.
- the shortest T 0N time that the microcontroller can deliver is therefore longer than the minimum time required for the PWM signal, so that an additional pulse shaping stage between the PWM output of the microcontroller and the semiconductor switch is required for the hold mode, with which the T 0N time of the microcontroller can be shortened accordingly. Furthermore, these pulse-shaping is required for the T ON -time can be finer resolution by the step value of the holding current, and thus (2 Ha P ⁇ te ⁇ l ⁇ Ha te) of the holding power - to be minimized.
- Fig. 3 shows the structure of this pulse shaper stage.
- the negated PWM signal (open collector) of the microcontroller is connected here to a capacitor 11 via a decoupling diode 10.
- the voltage across the capacitor 11 is monitored via an inverter 12 with a Schmitt trigger input.
- the switching level is approx. 60% of the supply voltage V cc .
- up to four outputs Q1 - Q4 of the microcontroller with open collector are controlled. These outputs discharge the capacitor 11 via the stepped resistors R1 to R4. As soon as the voltage across the capacitor has dropped below the threshold voltage, the semiconductor switch 3 is driven via the inverter 12.
- the negated outputs Q1 - Q4 of the microcontroller can be switched to opal collector transistor stages 13 with discharge resistors R1-R4, the pulse width of the control signal of the semiconductor switch 3 being determinable by the PWM output and the RC combination.
- Dynamic determination of the input voltage is required to dynamically determine the PWM ratio.
- the voltage measurement takes place on the DC side behind a bridge rectifier (not shown in more detail):
- the input voltage is filtered via a T-filter, which is arranged in front of the microcontroller.
