Definitions
- the application is based on a high-voltage switch for ignition systems of internal combustion engines according to the type of the main claim.
- a high-voltage switch is already known from DE-US 4032131, which takes over the function of an ignition voltage distributor when the high-voltage distribution is at rest.
- This high-voltage switch consists of semiconductor elements which have light-sensitive zones and the light-sensitive zones are controlled by light-emitting elements in such a way that they switch through at a predetermined time, for example in accordance with the firing sequence.
- the individual semiconductor elements are breakover diodes, which are arranged in a cascade circuit.
- breakover diodes offer the advantage that when the breakdown voltage is reached, the high voltage built up on the secondary side is suddenly switched through to the spark plugs, as a result of which voltage loss due to possible shunts, for example due to soot, is avoided. It is not necessary to irradiate the entire cascade circuit with optical energy. It is sufficient to irradiate only a part of the breakover diode cascade, so that only a part of the breakover diodes is switched by means of light and the remaining breakover diodes turn on when the predetermined voltage is reached, and a desired increase in splitting effect is achieved.
- the arrangement according to the invention with the characterizing features of the main claim has the advantage that the first illuminated partial stack of the breakover diodes has a low temperature response of the breakdown voltage. At the same time, however, these breakover diodes have a strong temperature response of the breakdown currents. They are therefore very suitable for the illuminated part, since here they do not act in the sense of the breakover diode, but as light-triggered switches.
- the division effect is retained by the arrangement of the non-illuminated part of the high-voltage switch. This results from the "overhead" ignition of the non-illuminated part of the high-voltage switch.
- the measures listed in the subclaims enable advantageous further developments and improvements of the high-voltage switch specified in the main claim. It is particularly advantageous to use breakover diodes with low and narrowly tolerated breakdown currents for the non-illuminated second partial stack of the breakdown diode cascade, since the breakdown diode's function is thus maintained for the division effect.
- the combination of these two types of breakover diodes has the advantage that a low temperature response of the switch is achieved and the number of semiconductor elements can be reduced.
- the two partial stacks of the high-voltage switch can also consist of two discreet, separately packaged parts. It is only necessary to ensure that the connection length between these cascade parts is as short as possible. drawing
- FIG. 1 shows an ignition switch with a high-voltage switch made of two stacked partial stacks
- FIG. 2 shows an ignition circuit with a high-voltage switch and cascade parts packed separately.
- FIG. 1 schematically shows an internal combustion engine with an ignition system and static high-voltage distribution, only two ignition coils being shown, but a large number of further ignition coils being possible.
- a battery voltage U is applied to a primary winding 10
- a secondary winding 14 of the ignition coil 11 is grounded on the one hand and is connected to a spark plug 17 and 18 on the other hand in each case via a high-voltage switch 15 and 16.
- the high-voltage switches 15 and 16 are each divided into two partial stacks 15a and 15b or 16a and 16b, the partial stacks 15a and 16a being on the side assigned to the ignition coil and the partial stacks 15b and 16b being on the side assigned to the spark plug.
- the partial stacks 15a and 16a are actuated at their light-sensitive areas via a light-emitting source, for example a light-emitting diode, by the control device 13 in accordance with the ignition specification and thus pass on the ignition voltage to the spark plugs.
- a light-emitting source for example a light-emitting diode
- the light transmission from the light-emitting element 19 to the partial stacks 15a or 16a to be illuminated takes place by means of an optical fiber rod 20.
- an arrangement of the individual partial stacks is also conceivable. the non-illuminated partial stack being arranged on the side assigned to the ignition coil and the illuminated partial stack being arranged on the side assigned to the spark plug.
- the ignition circuit is constructed exactly as in Figure 1, so that the same reference numerals are used for the same parts.
- the high-voltage switch has been given other reference numerals, since in FIG. 2 the high-voltage switch consists of two separate sub-stacks 21 and 22 or 23 and 24. With this separate arrangement of the partial stacks, it is only necessary to ensure that the connection 25 or 26 between the partial stacks is as short as possible in order to keep line capacities as low as possible.
- Tilting diodes of the unlit partial beam have relatively low tipping currents between 1 mA and approximately 15 mA over the entire temperature range. These low breakover currents are required for the function as a breakover diode with a splitting effect. Breakover diodes with relatively low breakover currents each have a strong temperature response of the breakover voltage, i. H. the breakdown voltage decreases with increasing temperature. If the cascade circuit consisted only of the breakover diodes with these properties, the high temperature response would require a large number of breakover diodes in order to be able to maintain the desired total voltage over the entire temperature range.
- breakover diodes with a low temperature response of the breakdown voltage as used for the illuminated part of the stack, have a strong temperature response of the breakdown currents, so that these breakover diodes are not suitable for realizing the distribution effect, but are advantageous for the light-driven part of the breakover diode cascade can be used.
