The ISL6315 two-phase PWM control IC provides a precision voltage regulation system for advanced loads up to 60A to 80A. Multiphase power conversion is a marked departure from single phase converter configurations employed to satisfy the increasing current demands of modern microprocessors and other electronic circuits. By distributing the power a
A Half Bridge Buck Boost Converter with high side N-type MOSFET
The buck-boost converter is of value where the output and/or input voltages vary to such an extent that on occasions a buck converter is needed, while on other occasions a boost converter is needed. An example (that will be described further in another project) is that of a battery charger for a number of different battery types, voltages and capa
DC Analysis of a MOSFET Transistor Circuit
When doing DC analysis, all AC voltage sources are taken out of the circuit because they`re AC sources. DC analysis is concerned only with DC sources. We also take out all capacitors because in DC, capacitors function as open circuits. For this reason, everything before and after capacitors are removed, which in this circuit includes resistor, Rs.
Dimmer With A MOSFET
This circuit shows that dimmers intended for use at mains voltage do not always have to contain a triac. Here, a MOSFET (BUZ41A, 500 V/4. 5A) in a diode bridge is used to control the voltage across an incandescent bulb with pulse-width modulation (PWM). A useful PWM controller can be found elsewhere in this issue. The power supply voltage for drivi
Power MOSFET Bridge Rectifier
The losses in a bridge rectifier can easily become significant when low voltages are being rectified. The voltage drop across the bridge is a good 1. 5 V, which is a hefty 25% with an input voltage of 6V. The loss can be reduced by around 50% by using Schottky diodes, but it would naturally be even nicer to reduce it to practically zero. That`s pos
8-Channel High-Current Opto-Isolated Open-drain MOSFET Driver motor Board
Embedded I/O board provides isolated high voltage switch inputs and eight high current high voltage DC outputs using optically isolated, open drain N-MOSFET transistors as solid state relays (SSR) for controlling resistive or inductive loads, including motors, relays, solenoids, heaters, valves, fans, high power lamps and LEDs and blowers..

It would be convenient to use momentary contact push button switch to turn ON and turn OFF your Raspberry Pi (RPi). A press of button should apply power to micro USB header, and keep it ON while Raspberry Pi initializes and starts its application..
Controlling Stepper Motors Using Power IO Wildcard MOSFET Driver
For maximum efficiency, set MAX_STEPPERS equal to the number of stepper motors that you are controlling (but never more than 4). Motors are referred to by their indices 0, 1, 2 and 3. On the QCard there is a trade-off between the number of motors being controlled and the maximum stepping speed, limited by the available processing power of the...

Silicon Carbide MOSFETs Demonstrate Superior High Frequency Performance Under Hard Switched Conditions
Comparing the performance of 1200V silicon carbide (SiC) MOSFETs with 1200V silicon MOSFETs and IGBTs at high frequency is critical to establish the difference in device losses and power-handling capabilities between the technologies. Using a demonstration platform that can be set to emulate a given set of parameters (e. g. , switch voltage,...

Ultrasonic distance finder circuit
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is measured. There are three main categories of distance measurement methods in use: a) By...
Simple Metal detector circuit with CD4030
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to find something potentially valuable, hidden a few centimeters below the soil. So many...
Fully automatic watering circuit for flower pots
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This circuit comes as a solution to this problem. Depending on humidity of the pot at...

Sub-Harmonic Bass Converter for Electric Guitars
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound, such as filtering or distortion. Instead, a frequency division system produces outputs...
Echo Depth Sounding Sonar for Boats
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the calibration of the rope. This arrangement still exists in some yachts. The big...
