High efficiency push-pull inverters minimize undesirable energy losses usually resulting from simultaneous conduction and imperfect switching of the transistor switching means. In each of the disclosed circuits, a saturable inductor and a diode are connected in parallel and across the base-emitter ...

High impedance (High-Z, Hi-Z) pin-A pin that is characterized by having a high impedance which effectively removes its influence on the electrical circuit it is connected to. It is not actively driven and is “floating” unless another external device or circuitry (pull-up/pull-down) is d...
improve the load capacity of the circuit and the speed of the switch. Open drain output: the output terminal is equivalent to the collector of a transistor. In order to get high level need pull-up resistance. Suitable for do type of drive current, its ability to absorb the current...
Pull-up Resistor During Switching As we can see, when the push-pull buffer is sourcing current (green arrow), the pull-up resistor is in parallel with a low-resistance transistor channel, so it should have minimal effect on the current being sourced by the buffer circuit. When the buffer ...
German Patent DE1939276 Kind Code: B2 Abstract: The control circuit for push-pull transistorized inverter comprises a clock pulse generator for producing two 180 deg. phase-shifted pulse trains of the same frequency, and two switching circuits formed from a control transformer, two switching transi...
