Definitions
- the present invention has for object a method and high voltage increaser device for I.C. combustion motors.
- the invention finds particular even if not exclusive application in the sector of the ignition systems with capacitive discharge for I.C. motors.
- This technique requires beyond to the bobbin for high voltage connected to the ignition plug, a transformer that works to frequency more or less high for loading the to the capacitor a quantity of current that reaches the discharging capacity having at disposal a lower voltage.
- This transformer that is made to work at frequency more or less high is well known as "high voltage increaser". It is clear that a device of this feature is cumbersome and expensive because the assembly implicates the generator, the high voltage increaser, and the system of ignition in which the high voltage bobbin is comprised.
- the entire device is simplified and compacted making it maximally efficient and producible at very low costs.
- the function of further increasing the voltage to the high voltage bobbin is realized by means of a high voltage stopping diode, set between the primary/s winding/s and the secondary/s winding/s in order that: - in a first phase to allow to the current to flow from the secondary winding toward the capacitive system; - and in a successive phase to prevent this this current to flow, the stopping diode being polarized inversely, constraining the current via hearth to determine the discharge in the ignition plug .
- the device comprises the integration with the primary winding of the discharging capacity by means of a capacitor winded element with controlled impedance, of the type having a bobbin coaxial with the secondary winding, said windings being realized utilizing electric conductor sheets or layers alternated with dielectric insulating sheets or layers, in which in at least two of said winded electric conductor sheets or layers, is elicit respective couples of opposite terminals electric connections, constituting the primary winding in order to include in it also the capacitive function.
- Figure 1 represents a view of an electric schema realizing the invention in preferred solution utilizing an integrated device of inductance and capacity.
- Figure 2 represents a view of an alternative solution without utilizing the integrated device of inductance and capacity disclosed in figure 1.
- Figure 3 represents the respective diagram of actuation in the phase of loading the capacity ⁇ lp-t (current intensity/time, on the system of primary winding) ⁇ and ⁇ Vc-t (voltage/time on the capacity) ⁇ .
- Figure 4 represents the development of the respective sheets of the integrated element of inductance and utilized capacity in the schema of Figure 1.
- Figure 5 represents a schema of the entire device comprising the primary winding and secondary winding where the primary is an inductance and capacity integrated device disclosed in Figure 1 with ferromagnetic soul.
- the integrated system is substituted by means of traditional which means that have: - a power line, from the generator (GEN) through generator output diode (D1 ): - with a first branch by means of diode for high voltage (D3) with cathode connected to the cathode of said generator output diode (D1), that connects to the secondary winding (Ls) and to the plug (Cd); - with a second branch that is connected to a primary winding (Lp) which opposite terminal is connectabie to earth by means of electronic switch that implicates periodical on/off actions (S) as for example a bipolar transistor or a "MOSFET", with bridge by means of a connection to the anode (A) of an SCR, which GATE (G) is controlled by means of control device (10); - with a third branch, intercepted by a diode (D4) with cathode to earth, being foreseen the connection with the intermediation of a capacitor (
- the current “lp” flows from the generator (accumulators battery or other generator at low voltage) through the generator output diode (D1) to the terminations (1) and (2) of the winded sheet of the capacitor winded element for controlled impedance (that act as as a inductor (Lp Fig.1) ⁇ or by the primary inductance (Lp) in Fig.2 ⁇ and the switch "S” that is closed; the current (lp) flows as by Fig.3 (to - t1 ; t2 - t3; ), until opens “S", (t1 - t2; t3 - t4; ), being (Ls) magnetically coupled with (Lp), being two coaxial windings with central nucleus of ferromagnetic material (M), the brusque current variation in the primary winding (Lp) generates an high potential in the secondary winding (Ls) that polarizes directly the high voltage stopping diode (D3) and the diode (D
- the secondary winding (Ls) being magnetically coupled with (Lp) and having a inductive value very high if compared to (Lp) is seat of an electromotive induced force from the current variation on (Lp) that polarizes inversely the high voltage stopping diode (D3) and with such a value to prime the spark on the ignition plug (Cd).
