Definitions
- the present invention relates to a self-oscillating DC-DC converter having a first and a second input terminal for applying a DC input voltage, a first and a second bipolar transistor, each bipolar transistor having a control electrode, a reference electrode and a working electrode, at least one coupling capacitor, wherein a first Switching path is formed by the distance working electrode - reference electrode of the first bipolar transistor, and a second switching path through the distance working electrode - reference electrode of the second bipolar transistor, wherein the first and the second switching path with respect to the DC input voltage connected in series, a rectifier whose output to a first and a second output terminal for providing a DC output voltage is coupled. It also relates to a method of providing a DC voltage to such a self-oscillating DC-DC converter.
- the present invention is based on the finding that the variations of the switch-off delay, which occur in a barely controllable timing compared to MOSFET transistors in bipolar transistors, can be counteracted effectively by controlling the bipolar transistors via a special, pulse-shaping timer he follows.
- the present invention in particular, overcomes the problem of variations in the current gain of various transistors within a type.
- the reference electrode of the first bipolar transistor is coupled to a first reference potential and the reference electrode of the second bipolar transistor to a second reference potential, wherein parallel to the distance control electrode - reference potential of the first bipolar transistor, a first diode and parallel to the distance control electrode - reference potential of the second bipolar transistor a second diode is coupled, wherein the first and the second diode in conjunction with the respective bipolar transistors lent demagnetization of the transformer lent (freewheeling phase).
- Fig. 2 shows the time course of some sizes using the example of the switch Ql of Fig. 1.
- the time course of the corresponding variables at the switch Q2 corresponds to those shown in Fig. 2, it is only offset by half a period.
- the rectangular shape of the collector-emitter voltage U CE of the transistor Ql is clearly visible.
- the voltage U CE returns to almost zero.
- the regions of negative amplitude of the collector current Ic are due to the inverse or freewheeling current
- the negative amplitude of the base current I B at time tl results from the outflow of storage charge from the base terminal when the base-emitter forward voltage drops below Ü BE over R3 and is used to clear out charge carriers from the base of the switch Ql and thus a defined shutdown of the transistor Ql.

Toujours selon l'invention, les deux sections de commutation sont branchées en série. Le convertisseur est également muni d'un redresseur (GL1) dont la sortie est connectée à deux bornes de sortie. Selon l'invention, le convertisseur CC/CC comprend en plus : un transformateur (TRI) comprenant un enroulement (PW) primaire, un enroulement (SW) secondaire et au moins un enroulement (StW1; StW2) de commande. Selon l'invention, l'enroulement primaire est connecté entre une liaison des deux sections de commutation et le condensateur (C4; C5) de couplage, l'enroulement secondaire est connecté avec l'entrée du redresseur (GL1) et à chaque transistor (Q1, Q2) bipolaire est associé un enroulement de commande qui est connecté à l'électrode de commande du transistor bipolaire correspondant. Le convertisseur CC/CC comprend également au moins un élément (Z1, Z2) de temporisation qui est connecté entre l'enroulement de commande correspondant et l'électrode de commande. L'invention concerne en outre un procédé de fonctionnement du convertisseur CC/CC.
