In AC motors, the rotor receives electrical power by Induction exactly the same way as the secondary of a two winding transformer receives its power from the primary. That's why such motors are known as Induction motors. In fact, an induction motor can be treated as a rotating transformer i.e. one in which primary winding is stationary but secondary is free to rotate....
Pakistan's progress in solar PV based energy generation My comments about publishing in Renewable and Sustainable Energy Reviews The publication process was very slow. It took more than a year to get the first review. The user interface with the Elsevier journal submission is excellent. ...
The PWM channel used in thedSPACE has four channel and each channel is connected to one pin of slave I/O port. The channel I/O mapping is given below. As seen the output of channel 1 is available on pin 5, channel 2 on pin 10, channel 3 on pin 24 and channel 4 on pin 11. The ground pin is pin #1. ...
The use of dspace DS1104 for data acquisition is explained in this blog post. The experiment is to use ADC channel of DS1104 to record the waveform of grid voltage. In order to record the grid voltage, a step down transformer is used that steps down the 110V/60Hz to 5V/60Hz. The secondary low voltage side of the transformer is connected to the ADC...
In PV grid connected inverter, in order to inject the current at unity power factor we need to know the polarity of the grid . To do so various solutions exists. Among these solutions is the use of optocoupler. I have verified the use of 4N26/4N37 for the said purpose. The circuit is very simple and its working is given below. ...
The solar module i am using is SANYO HIT-N220A01 and its salient features at standard testing condition are as follows. ...
The dSPACE is used widely now a days to validate the theoretical algorithms. The data file is usually in Microsoft access format that can be plotted using MATLAB. The data extraction is particularly helpful in genrating IV and PV curves based on the experimental data. ...
Optocouplers are widely used in power electronics to isolate the power stage with the control area. Every optocoupler has a limit of operating frequency. Recently, while working with my hardware setup i noticed that the optocoupler i am using is not good for high frequency. Below are the results i obtained while trying to switch my 4N26 optocoupler. ...
