| titleOfInvention | DC to DC converter |
| abstract | In a conventional DC-to-DC converter of the single-ended type, it is usual to use what is often called a snubber network to eliminate high- voltage transients due to the fast switching pulse edge which occurs when the power or switching transistor is switched off. Such a network usually involves a capacitor in series with a resistor connected across the transistor, which resistor is shunted by a diode. In one circuit embodying the invention the capacitor (C1) is of the order of ten times the size of that usually used, with the result that in addition to the elimination of leakage transients, the core of the transformer (TF2) is totally reset, which enables the whole of the flux swing possible with the transistor to be used. In addition a much higher pulse duty cycle is usable than in a conventional circuit. In another arrangement (Figure 3) the capacitor is even longer - e.g. of the order of 100 times the size usually used, with a further switched transistor (TR4) in series with it. This eliminates the dissipation of energy which usually occurs in the series resistor. <IMAGE> |
