1323654 Transistor oscillators TEXACO DEVELOPMENT CORP 28 Jan 1972 [1 March 1971] 3997/72 Heading H3T An invertor including a pair of transistors 27, 28, a saturable core transformer 26 with a regenerative feedback winding 31, and an output transformer 21, includes additional windings 37, 40 to absorb leakage inductance effects in the output transformer. The windings 37, 40 are connected in series-aiding relationship so that spikes (11, Fig. 2, not shown) on the output waveform are substantially removed, in order to protect the transistors. The switching times of the transistors are also slowed by the feedback through transformer 26 to T27, T28 bases. Capacitor 41 is selected to prevent oscillation. |
