I need a simple circuit to test a 2n3055 transistor driver#

The frequency of operation in this circuit is determined by the capacitor across the transistors emitter and collector, experiment with the value of this capacitor to find the best performance, this capacitor have to be a good film or foil type (MKP/MKT) The transistor used in this circuit should not have a voltage rating higher than 250V, due to the higher base current needed of higher voltage rated transistors, this might in some cases cause problems where the self-resonating circuit can no longer drive the transistor.ДЄt voltages higher than 12 VDC input, the components will dissipate a lot of heat and the 2n3055 transistor is most likely to burn as it is not rated for more than 15 A and it has to be derated even further for case temperatures above 25 oC.

In plate 10 we use a high-power Mj2955 (the compliment to the earlier 2N3055) with a TIP42 PNP transistor to form a Darlington transistor. When used as switches the transistors are used in the saturation mode where additional base-emitter current will produce no additional collector emitter current. The values hfe represents DC gain - a small base-emitter current creates a larger emitter-collector current.

This too forward biases the base-emitter junction. Push Sw2 this allows current from GND through the emitter that spits to form Ib and Ic for the NPN transistor. This combines with the collector current to produce the emitter current back to the 12-volt supply. Push switch Sw1 current flows from GND through R1 and forward biases the base (B) with respect to the emitter. Sink and source are important to know when connecting programmable logic controllers (PLCs) used to control machinery in industry. With the NPN transistor on the right the switch is in the ground side of the load and is said to sink the current. Operating as a switch to turn the motor ON-OFF the PNP transistor is located in the +Vcc side of the load and will source the current. Note the position of the transistors in relation to GND, the +12-volts, and the load in this case DC motors. Note the arrows dictating current flow - with the PNP the collector current (Ic) is from collector (C) to emitter (E) while the NPN Ic is emitter to collector. Note current flow in these illustrations is from negative to positive. Plate 3 illustrates the typical electrical connections for both PNP and NPN bipolar transistors on a negative ground micro-controller system.
