Dear Sir, I finally need to filter the high voltage pulsed output. Basically, I am designing a PSM (Pulse Step Modulation) high voltage power supply. The output of PSM "forward block system" is a high voltage pulsed output, and its input is a PWM (pulse width modulated input). To control the...
I am designing a DC High voltage power supply, using PSM technique. I need to control it in a feedback loop, for which i need a resistor divider at the final output. Output is a pulsed high voltage around 1000 Volts of frequency 20 kHz.
This high voltage pulse o/p needs to be attenuated down...
I am trying to implement ethernet lite core on FPGA using microblaze. I have attached the SDK C source file. Remote address writen in file is my PC MAC address. I am trying to send 8 bytes of data. I did not find any response on Wireshark software. Is there any IP settings to be done on PC side...
I have a pmod enc ethernet controller card frm digilent. I have successfully interfaced it with spi protocol. Now when i send ethernet frame no response on wireshark tool i can see. Following cmds were send frm spi one by one:
1. I first configured automatic mac address insert, by settting ECON2...
Hello, i dont have any signals frm LCD entering to fpga (input to fpga). There are 4 signals only frm fpga to LCD. They are R/S, EN, W/R and the 8 bit data signals. These 4 signals are 3.3V i/o levels. I gave 5V power frm another source, not frm fpga and connected all the gnds together. The...
I am trying to interface JHD204A LCD display with my FPGA board. The problem is that LCD works with only 5V power supply, and my FPGA supplies 3.3V only. I supplied power from another source of 5V, and connected the grounds of both togeteher. LCD display is showing bright light, but no data is...
I connected a negative bias at the -V pin of OPAMP instead of ground, and it is working perfectly. The circuit image is attached. For a input of 0 to 1V, it gives a output of 0 to 1V exactly. Thanks dear for your kind support. Thank you very much.
But one issue is that if I increase input...
I need to design a optocoupler circuit as shown in the attached datasheet of IL300 optocoupler IC. I designed the circuit as shown in the first page of pdf. I used OPAMP OP-07. I did'nt used the output OPAMP in the circuit. I applied a sine wave of few hundred hertz at the input. It gets...
