I have to make clear on this BJT type to differentiate among the other types of transistors family such as FET (Field Effect Transistor), MOSFET (Metal Oxide Semiconductor FET), VMOS (Vertical MOSFET) and UJT (Uni-Junction Transistor).
One of the popular method is to use the Bipolar Junction Transistor (BJT) or we just called it transistor in this tutorial. Q1 and Q2 can be any type of power FET.Most of microcontrollers work within 5 volt environment and the I/O port can only handle current up to 20mA therefore if we want to attach the microcontroller’s I/O port to different voltage level circuit or to drive devices with more than 20mA we need to use the interface circuit. T1's secondary and primary windings, a 12.6 to 440 V power transformer. With a rectifier and filter, this inverter can deliver high-voltage AC or DC up to several hundred volts. As a result, the MOSFETs alternate between operating in the cut-off and saturation areas. By biassing the MOSFET with a square voltage waveform between its gate and source terminals, the DC voltage(VDC), is turned into an AC(VAC) voltage with the same amplitude level. The figure shows how the switching behavior of MOSFETs may be used to construct chopper circuits.

The input signal's emitter current goes to the collector current, which then flows through the load resistor RL, causing a high voltage drop across it. This forward bias is maintained irrespective of the signal's polarity.īecause of the low resistance in the input circuit, every minor change in the input signal results in a large change in the output. When a DC bias voltage is provided to the emitter-base junction, it remains forward biased. A transistor functions as an amplifier by amplifying a weak signal.
