trigonometric optimization
Dear All,
I'm working on an inverter and to eliminate harmonics in output voltage and current i have to optimize a solution of a system of nonlinear trigonometric functions and i don't know how, Newton-Raphson iteration method is too difficult with this...so I really...
Hi Abdallah;
are you sure it is a valve? Because i searched for the (WMW Hekert) company and it works in milling, drilling, grinding, lathes and rotary tables.
the work "Werkzeug machinenen fabrik" written on the name plate means "
Machine tool factory".
Please try to check that the name...

s5 communication cable
ear All,
I'm having a problem with communicating the S7-200 PLC with PC because i don't have the communication cable and it's still expensive for me to buy.
Have anyone any schematic for this cable?
Note:
PLC communication port is RS232...I tried to use old S5 cable but...

irf540n circuit
Dear All,
I face a problem with the amplifier circuit of 5 level multi level inverter circuit.
The main problem is summarized in that i need to drive number of MOSFETs (IRF540N) and I found that if i used an amplifier circuit will be good, but when i tried to drive the MOSFET i...
Need Help with PIC18F452
Dear All,
Please help me to write a program with C or assembly for firing thyristors of Full wave Inverter.
I have 4 thyristors (1, 2, 3 & 4)
the main idea is to fire (drive) the gate of thyristors 1&3 at a specific time while 2&4 are off, and vice verse.
Can you help...
Dear blueroomelectronics,
You can say that i want to build a UPS for a final year engineering project, about volts I want to invert 24 Vdc from batteries to 110 Vac and 220 Vac and a range between them if it could be possible.
about amperes, you can say i just want a value like i can draw from...
Dear All,
I'm going to make a power electronics multilevel inverter (DC --> AC inverter) based micro controller (PIC), and I'm a beginner in micro controller design and programming.
Please if there is anyone can help me to understand it well and how to choose the best micro-controller to do the...
plc for beginners
Dear All,
I'm new here and I thought it'll be good to start with something useful i can share with you.
Here's a link for Mitsubishi PLC training software, it's useful for PLC beginners.

Hi All,
Please Help me with my project (Final year Engineering project) and it's about Multilevel Inverter (Theory and Application)
Please if there is anyone know anything or have any e-books about the subject please help me.
Dear All,
I need your help in my final year project.
I thought of making a water filter in water treatment station using PLC but when i made a survey i found that the filed instruments are very expensive like pressure Tx. and level sensor that's number 1.
2 - I need to make a kit for it and i...
