I have to model and simulate 3phase inverter in PSpice 9.1 or OrCAD 7.2. Which one is better for that application?
Hi to all! I've a question relating this interesting argument. I would like to use a rectifier bridge (with capacitor) to rectify a AC single phase supply and then use the DC BUS that I've obtained to drive a motor with an inverter. If my suppositions are correct the resulting voltage applied at the motor will be lower than using a DC BUS obtai
Hi! can anybody help in building a pwm for controlling a 3phase inverter for permanent magnet synchronous motor on simulink, any info will go along away. thanks
Dear all i need a recomendation for an IGBT suitable for my project "3phase inverter" .. 220volt,50HZ Thanks
Is it possible by using three 12V dc to 220Vac,1550W inverter by supplying them 12Vdc parallal circuit from a 50Vdc source, can I get 3phase AC output.:D :cry:
Shall we use an AC motor through an inverter with the suitable range of capacity, say if motor is 1.5KW then it would be run through 1.5KW or more inverter and/or if motor is 3phase 3KW then it would be run through 3phase 3K.W or more cap inverter :confused: :?:
Hi, Can I get 3phase from 3phase to single phase transformer if I give single phase input . is there is any easy way to generate 3 phase from single phase?
i am woking on 3phase pwm on inverter need your help guys???
now im doing my project now im facing a problem in triggering switches how to generate svm pulse for 5 level 3phase cascaded multilevel inverter fed to induction motor drive plz any one send matlab\simulink model
I`ve made a 3phase frequency invertor. The turning speed is good, but there are a lot of vibrations and distortion in the engine. I`m using PWM modulated pulses 500us each. For 50Hz this must be around 2kHz changing frequency. My dead was 2.2ms but I dropped it to 1.3ms without any result. I`ve tried with mid alignment of the pulses. It became be
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. i am s
Hello, I need to synchronize an inverter to the power grid. So far I can easily track 3-phase voltages with high immunity to noise and other power failures. I am using a abc->dq conversion (3phase to 2phase, rotating frame) and with this I can easily track the phase, the sequence and peak voltage. I need to track now single phase signals. I h
I build simulation model of an sigma delta modulator (analog input digital output) in order to control transistors in 3phase full bridge resonant inverter. In negative feedback loop I have 1bit D/A converter and it gives +-5V. Reference voltage is 5V*sin(2*pi*50Hz*time). I couldn't rise this voltage at 220V because of op amp input is max 30V (V+ -
OK I got it! Here is what anu looking for! A three phase induction motor controller! -- 3phase Induction Motor Controler II -- library IEEE; use IEEE.STD_LOGIC_1164.ALL; use IEEE.STD_LOGIC_arith.ALL; entity inv3pa is Port( speed_clk,vector_clk,inhibit_sw,over_current : in std_logic; port_U,port_V,port_W,port_I
Greetings all, I am a new member to the forum currently working on a phase converter project for one of my 4th year classes. What I hope to accomplish is a single phase 120Vac input 3phase 60hz 208l-l output 1kVA phase converter. The topography I have already designed (and submitted as a proposal so the specs have to remain fairly similar
I have simulated the PV system connect to grid help me the feedback PLL to control the inverter 3phase 2 level (6 IGBT/diode) I'am doing from
For the purpose of building it; You need to convert Single phase AC to DC. Then by using three phase inverter you should be able to get 3 phase output. Yes you can do it with transformers that you can find phase shift transformers. Not sure if they exist. I have seen three phase, phase shift transformers though. Mostly, it would be done by AC(sin
