AC servomotors are in fact AC machines, but supporting extreme max. currents, loads, and speed. Having higher max. current the acceleration is higher (can start and stop much faster). Might have different constructions, like brushless DC machines, when instead of having a DC machines where the current is inverted by the brashes, you do that by ha
There may be an ambiguousity of the term but an usual H-Bridge made of four controlled switches (BJT, FET, igbt) is actually a full bridge respectively a four-quadrant motor controller that performs Forward, Backwards, Stop and brake.
l298 data sheet contain application circuit diagram , l298 + l297 = a good driver for both dc as well as stepper motor. if you are using dc motor and dc motor is running in one direction only then , mosfet / igbt will good choice .
Hi friends, How are you? I'm new here. Please excuse me, I'm so directly. I have a problem, therefore, beg you to help me. I have expanded an electric Power steering (EPS) UNIT from a VW passat. I have disassembled this Unit to get the 12 volts AC induction motor. Now I want to build a frequency converter for it. I think I have the nec
Gents, I am working on a gate driver for a 3 phase inverter to drive an AC motor, everything seems to be working fine when the motor is stationary but as soon as i start the motor i have phase3 peak lopping (peak shaving). the gate driver output is +-15V, +-30A, 4Watts maximum, and i am using it to turn (...)
Starting torque takes more current and low ESR. Look at the voltage drop on your driver and consider better drivers. For BJT drivers, a current gain of 5 was normal and 10 was good. For fast switching of MOSFET the current gain of 50 is normal , and 100 to 200 is good and maybe more in igbt. Even though static gate current (...)
Friends, my project: speed control of BLDC motor (square wave BLDC)... my motor(load) specifications are: 24VDC(for inverter) 0.25HP 3000RPM and by calculations it shows current rating will be 8Amp so the inverter should be designed for this specifications... with the help of datasheet i designed the mosfet gate driver circuit, i (...)
for driving brushless motor u can not use ULN series ICs. it'll give only -ve (GND) supply to the motor it can't give +ve supply. because it has only open collector output. u need full bridge which can give bot +ve and -ve to motor terminal pins. u can develop ur own 3ph H-bridge using MOSFET or igbt. or u can go with (...)
Also look at IR (International Rectifier) website, they have high side drivers, low side drivers and full bridge drivers to interface between the micro and the igbt. (IgBots!). There are also a lot of application notes to look at. A common frequency to use is 16KHz. This can only be heard by bats, dogs and young children. (...)
You have not indicated the voltage and power rating of the motor. If it is just a small motor of 50V and less than 2 A, You can drive it with a Microcontroller of the motor control family(16f684a) or the 18f series with dedicated motor control peripheral. You would also require an H bridge as an interface between PIC and (...)

hi i need some basic details about igbt(ir2110)before that i know the motor control using pwm pic controller but my new project using igbt baesd control the motor , already search the basic concept and how to use the igbt ic but i can't got clear Explanation i mean how to use the igbt (...)
Dear friends in all circuits that you use mosfets or igbtS or FETS you should use a resistance in parallel with gate to source . because their gate is isolated and in gate to source we have a little capacitor! if this capacitor going charge , cant going discharge and mosfet likewise will on. if you use a gs resistor(usually 39 K) you can improve i
hi all i am new here , i was working the past 2 weeks to make PWM for an existing 240VAC 2200W but i will run it on DC 260V instead from 20 12V batteries for and electric car project i am working on i did try this circuit DPRG: A Simple PWM Circuit Based on the 555 Timer with 555 timer but

Obvious you need to use driver circuits in between MOC8102 optocoupler and the igbt transistor. You may change the MOC8102 optocoupler with a dedicated isolated driver, see for example Vishay VO3120 HCPL-3120:
Dear bianchi Hi Why not ? but after your microcontroller you'll need a current driver . ( e.g a mosfet or igbt or BJT ) . but before that, do you need to change the rotation , vector ? Best Wishes Goldsmith
hi. i am going to design a 3phase inverter motor driver with igbt's. designing of pwm generator- soft start-and dead time generator is already finished.and works good. but at the power stage i have problem with IR2112! when i try to simulate the circuit the coverage problem accrues.!! i think it's due to boot strap diode or capacitor. (...)
The motor is rated for 48V and 100A, but can handle up to 300A for one minute Hi if we suppose that you're looking for a mosfet with the same ratings then you can use some IRFZ44 in parallel together or perhaps a single mosfet with higher current handling ability ( or even igbt would suit your aim too ) For gate driver you can crea
Hi, You can have a look on Renesas Mosfet driverIC for better relaibility & features. Regards Puneet
I designed a 3 phase inverter with 6 discrete 600V rated igbts. I applied 10 KHz SPWM to the AC motor(2.2KW induction machine) via the inverter. DC bus is obtained from 380VAC rectification which is @537VDC at no load. I burnt some of the igbts at first try. Then i reduced DC BUS voltage to 300VDC. Tried again at first it didn't burn, but (...)
High-Side-driver is used to drive High-Side-Switch (e.g. mosfet or igbt), where one end of the switch is connected to Power-Rail, and the other end is NOT connected to ground.
It is conventional to use mosfets , but igbt's as well . So if chip outputs, timing and load current are suitable for particular driver we can put whatever we can fit into requirements. For MOSFET there is Vgs does matter for bjt - Ib , so lets give a current via resistor and bjt will be happy to switch as long as motor current is less than (...)
babatundeawe, regarding AC induction motor there are a lot of staff on freescale TI and similar manufacturers sites. You can get source code schematics to start your project. BTW, why are you shifting from dc motor to ac ? If you are new to this field i would recommend to buy VFD driver which costs 100-200 usd. Otherwise be prepared (...)

Hi, I'm doing a very complex internship and I realy want your help in designing a 2 phase, sinusoidal PWM inverter , 550V , 130 Amp., Iripple=30 Amp., igbt model no. is (FGL40N120AND), F sw.= 40 kHz, driver model(UCC37322), Output filter (L= 300 uH, C= 940 nF), load: linear motor. the designing of this system in based on a hard switched (...)
calculate and check out igbt losses both their switching and conduction losses, analyze the performance if it gives efficiency above 90% then it is good enough. Regards, Iftikhar Abid
1. The driver circuit dimensionioning hasn't to do with output rating rather than gate currents. High power tranistors haver usually larger gate capacitance and possibly use higher gate currents (depends also on the intended switching speed). 2. It's a threshold voltage, the gate driver supply must be considerably higher than it. 15 V is O.
Hi, we plan to use an Ir2113 as a gatedriver for our igbt. We plan to make an H-bridge using igbt for our AC motor. We plan to switch the igbt's on and off such that our 220DC supply will become AC w/ varied frequency. We've already seen the datasheet of IR2113, and followed the circuit that was there for (...)
After applying 200VAC from the igbt driver, all we hear is a clicking sound. it doesn't turn on the compressor. any suggestions how to fix this? thanks!
Panel CB or fuse (for each of 3 phases used)> Contactor> Load But it does not seem a good match to step up a 5V signal to 12V @9Amp to drive a 500A 600V 3 phase rated contactor just to 240V bulbs.... unless just an academic exercise, when a better solution is 5V signal> {opto-isolator > MOSFET driver} or all in one package > igbt> 500A load .
How can we use H bridge circuit for DC motor as well as AC motor?? - - - Updated - - - For my final year project i am building composite driver circuit for DC as well as AC motor. So i get the information that H-bridge circuit(igbt,MosFET based) can work as chopper as well as inverter by giving PWM tecq.. Bu
