Make H-Bridge for controlling DC brushed motor with PWM. One bridge will control 1 DC motor. Bridge will have 3 inputs: A, B and PWM. A and B will be direction control while one PWM signal will control motor speed no matter in which direction it will spin..... -
At 9 volts the maximum stalled current of the motor types I`m going to use will be 700 mA. Since I`m not real experienced with this I want to check that I`m choosing good mosfets, I`m pretty clear on the rating, they say what current and voltage they can.... -

FETs can be found in the power section, LCD inverter, UPS, Amplifier, Monitor B+ and S-correction circuit, ATX power supplies and etc. When this component fails, one has to use a meter to test it to check if it is good, shorted, openor leaky. The meters can.... -
I have created an H-bridge PC with 4x floating gate drivers and 4x IGBTs (see attached schematic showing half of h-bridge). It works very nicely but I .... -

A while ago i run across this document which apparently tells how to wire mosfets in series to get higher voltages (pg 10-14). This is the only schematic i found so far that is actually working. The problem is that i can`t make more than 3 mosfets work, when.... -
The schematic is attached, I`d like to have a suggestion if any improvement could be made, in particular I`d need to add a reverse polarity connection protection. I`m not a MOSFET expert, but: from the schematic I take it that the logic level inputs (5 V).... -
None of those devices is very suitable. The drivers aren`t specified to operate with 3.3V gate signals, and although the typical graph shows that a.... -
This simple power mosfet audio amplifier circuit, with TL071C and 2 MOSFETs (IRF9530 and IRF530) can deliver up to 45 Watts on 8 © speaker. This schematic is based on Siliconix application and on variations of voltage on the 2 resistors that are serial.... -
This mosfet fm transmitter circuit is designed to be used for aligning FM radio receivers. It has a microphone amplifier with automatic gain control. The FM modulation is a voltage oscillator and the final stage is built with MOSFETs. A lowpass filter at the.... -
I`m trying to get an ignition coil to create sparks running it with a Mosfet powered by a 555 timer. The Mosfet is definitely switching. I checked it.... -
Using measured threshold voltage and Ids-Vds curves, we can then check how well first-order MOSFET theory holds up in real devices and get a practical feel of the limitation of first-order theoretical MOSFET equation. The MOSFETs we will use in this.... -
It can be simplified and you can leave out short-circuit protection if you wish. This circuit is a Mosfet-based linear voltage regulator with a voltage drop of as low as 60mV at 1A. The circuit uses a 15V-0-15V transformer and employs an IRF540 N-channel.... -
It is useful where the load needs to be switched on from one location and switched off from another. Any number of momentary (N/O) switches or push buttons can be connected in parallel.... -
The ISL6308A is a three-phase PWM control IC with integrated MOSFET drivers. It provides a precision voltage regulation system for multiple applications including, but not limited to, high current low voltage point-of-load converters, embedded applications.... -
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.... -
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.... -
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,.... -
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.... -
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.... -
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.... -
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.... -
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.... -
The circuit uses a total of six, 12 volt lead acid batteries to power the load. 3 batteries are wired in series to create 36 volts. The total discharge current is 30 Amps. 3 batteries are wired in parallel to create 12 volts The total charge current is 10....
