Definitions
- the invention relates to an ignition circuit according to the preamble of independent claim.
- the ignition frequency is usually determined using an R-C combination generated in conjunction with a diac which, when the Breakdown voltage the trigger pulse (ignition pulse) for discharging a capacitor effected via a thyristor as a switch through the primary winding of a transformer.
- the thyrister is ignited by a trigger pulse, which by a logic circuit or a ⁇ P controller is generated.
- the aim of the invention is to avoid these disadvantages and an ignition circuit to propose the type mentioned above, which is characterized by a simple structure.
- the proposed measures can be used to convert the network frequency Circuit, as they are provided in the known solutions, are dispensed with.
- the proposed solution is characterized by a very simple structure.
- the proposed measures ensure that shortly before the start depending on Type of transistor controlling the trigger terminal of the thyristor negative or positive Half wave of the supply voltage an ignition pulse for the thyristor through the transistor is triggered. This leads to a transfer of the in series to the primary coil of the Transformer switched capacitor and thus to a current flow through the The primary coil.
- the ignition is switched on by switching the supply voltage or by switching the Trigger pulse for the thyristor off and on.
- a resistor R100 is connected to a mains connection L. connected, which is followed by a diode D100.
- a resistor R101 connected in parallel to this, one freewheeling diode D101 connected in parallel with this and one also connected in parallel Series connection connected.
- This series connection is one by a primary coil 1 Transformer U100 and a capacitor C100 formed.
- Ignition electrodes Z1, Z2 are connected to the secondary coil 2 of the transformer U100, which are arranged in the area of a gas burner, not shown.
- resistor R100 and the diode D100 are one with the second mains connection N connected voltage divider circuit connected by the resistors R106 and R110 is formed.
- the connection of these two resistors R106 and R110 is the Base of a pnp transistor T101 and one of a diode D102 and a resistor R114 series connection connected. This series connection is the Emitter of transistor T101 and a capacitor C101 connected to the second network connection N is connected.
- the collector of transistor T101 is connected to the gate terminal via a resistor R102 of the thyristor T101 connected.
- the embodiment according to FIG. 2 differs from that according to FIG. 1 in that that parallel to capacitor C101, which is connected to the emitter of transistor T101 is, another transistor T102 is connected in parallel.
- this transistor T102 is connected in parallel.
- the base of this transistor T102 on the one hand via a resistor R113 with the diode D102 and in series with this switched resistor R114 and connected to an optocoupler IC100, the Main current path, or emitter is connected to the second network connection N.
- the control input of the optocoupler IC100 is connected to a via a resistor R112 Control voltage UB connected, the LED of the optocoupler IC100 continues with is connected to a control terminal OFF.
- the trigger pulse for the thyristor T100 which is used to control the U100 transmitter, shortly before the start of each negative half-wave of the AC supply voltage between the network connections L and N.
- the ignition spark between the ignition electrode Z1 and the ignition electrode 2 is through Discharge of a capacitor C100 through the primary winding of a transformer U100 generated.
- the thyristor T100 serves as the switching element, with the parallel to this switched diode D101 serves as a freewheeling diode.
- the resistor R101 discharges the Capacitor C100 after switching off the power supply.
- the resistor R100 and the diode D100 the capacitor C100 charged.
- the energy required for the Ignition pulse, which is transmitted to the electrodes via the transformer U100, is then in the Capacitor C100 saved.
- the resistors R100 and R106, the diode D102 and the resistor R114 the capacitor C101 charged. Via the voltage divider through the resistors R100 and R106 one hand and resistor R110 is formed, the voltage across the Capacitor C101 limited.
- the Transistor T101 since the base potential of the pnp transistor is above its emitter potential lies. At the end of the positive half-wave of the supply voltage, the base potential becomes less than the emitter potential of transistor T101, which is caused by capacitor C101 positive potential is maintained. The transistor T101 therefore becomes conductive and remains in this switching state during the negative half-wave of the supply voltage.
- FIG. 2 shows an example of what happens by short-circuiting the capacitor C101 through the transistor T102 connected in parallel with this, the formation of a Ignition pulse can be prevented.
- the ignition can of course also be switched the supply alternating voltage L N via a relay or an optotriac as well turned off.
- the transistor is switched T102 via an optocoupler IC100, the base of transistor T102 via the Resistor R113 if the optocoupler IC100 is not switched through during the positive Half wave of the supply voltage on one opposite the emitter of the transistor T101 is held higher potential and is therefore switched on and therefore the Capacitor C101 cannot charge.
- the thyristor T100 cannot be ignited because C101 can discharge via R102. So can also the capacitor C100 does not discharge.
- the proposed ignition circuits are characterized by only a few simple components and thus a small space requirement and high reliability.
