Implementing P-channel MOSFETs in an H-bridge circuit may look easy and enticing, however it may require some stringent calculations and parameters for achieving an optimal response. P-channel MOSFETs are usually implemented for load ON/OFF switching. The ease-of-use of P-channel options on the high side allows them to be very convenient for applications like Low-Voltage Drives […]
Newly Updated Circuit Projects:
Field-Effect Transistors (FET)
The field-effect transistor (FET) is an electronic device in which an electric field is used to regulate the flow of current. To implement this a potential difference is applied across the gate and source terminals of the device, which alters the conductivity between the drain and source terminals causing a controlled current to flow across […]
Capacitor Inductor Calculations
Inductors can be imagined as the opposite of capacitors. The main difference between a capacitor and an inductor is that a capacitor carries a protective dielectric between its plates, which inhibits the conduction of current across its terminals. Here it acts like an open circuit. On the other hand the inductance of an inductor is […]
How to Troubleshoot Transistor (BJT) Circuits Correctly
Troubleshooting BJT circuits is basically a process of identifying the electrical faults in the network using multimeters across the various nodes in the circuit. BJT troubleshooting techniques is a huge topic and therefore including 100 % solutions and strategies can be perhaps difficult within a single article. Basically, the user should know about a handful […]
How to Connect Transistors (BJT) and MOSFET with Arduino
The interfacing of power devices like BJTs, and MOSFETs with Arduino output is a crucial configuration which allows switching high power loads through low power outputs of an Arduino. In this article we elaborately discuss the correct methods of using or connecting transistors like BJTs and mosfets with any microcontroller or an Arduino. Such stages […]
Load-Line Analysis in BJT Circuits
So far we have been studying BJT analysis dependent on the level of β over their corresponding operating points (Q-point). In this discussion we will check out how a given circuit conditions can help in determining the possible range of operating points or Q-points and in establishing the actual Q-point. What is Load Line Analysis […]
