    Parametric voltage stabilizer circuit

    Thanks for the advice. I also tested it without 4.7uF input capacitor and it hardly made a difference. I also tried a shunt 1 nF capacitor with R537: it did not do much, just made so little. Also I put 22 uF large output capacitor at output: did not make a difference.

    Parametric voltage stabilizer circuit

    Hello, I (am supposed to) design mainboards for TV units. In our mainboard we need to add a parametric voltage stabilizer before panel supply. Here is the situation. Our power supply may be varying between 11.8V and 14.2V and our Panel accepts maximum 13.2V (Absolute maximum). So, the ideal...

    [SOLVED] Can we calculate the horsepower by only AC current flow in windings in AC motor?

    I saw this AC motor parameter calculator online: https://www.engineeringtoolbox.com/electrical-motor-calculator-d_832.html It says for 100 Horse power, in 90% efficiency, 0.9 Power Factor and 220 V AC supply, 300A current is needed. But when I calculate like: 220V AC * 300 A AC * 0.707 (sine...

    [SOLVED] How to design an efficient high power bilateral switch for this special purpose?

    As soon as possible. And yes, I have to do it in one cycle. If you meant the tolerance by 'residue' I don't think I have a big tolerance. The capacitors must be as equal as possible in voltage level when the process is done. I will use logic and analog structures to control this logic. Logic...

    [SOLVED] How to design an efficient high power bilateral switch for this special purpose?

    I need to design a system that equalizes the two capacitors on each side. There are two big capacitors in the system and they will be charging and discharging by out of the system. They might reach to 105V and down to GND at any time. We won't know that, I am only responsible for equalizing the...

    [SOLVED] TPS61196 LED Driver chip for high Voltage Backlight applications: What to do for prop

    Re: Using TPS61196 LED Driver chip for high Voltage Backlight applications Yes, regarding to my experience you should do two things: 1- Make sure that you soldered the chip right. Do conductivity tests for each pin. 2- Make sure your switching inductance Self Resonance frequency is at least...

    [SOLVED] 2D - 3D conversion in embedded linux

    We have a system that we can not change. Systems output is 2D video in DisplayPort format. Video is in 1080 p resolution and 120 Hz. We need to convert this 2D video to 3D in realtime. We will be able to get 3D depth map. Now, I have to prepare a preliminary design report. So I kinda have to...

    [SOLVED] TPS61196 LED Driver chip for high Voltage Backlight applications: What to do for prop

    Yeah sorry for that. I choose to share it with tinyupload because it was a PDF file. Will never do that again. I measured the LED string voltage 24V which is the supply voltage.

    [SOLVED] TPS61196 LED Driver chip for high Voltage Backlight applications: What to do for prop

    Thanks for the reply. However, my design is for 118 V, I assume you confused that I use reference design. You can see it **broken link removed**.

    [SOLVED] TPS61196 LED Driver chip for high Voltage Backlight applications: What to do for prop

    Using TPS61196 LED Driver chip for high Voltage Backlight applications I need to design a Backlight Driver which has to have high brightness. These are the equipments I have in the design: My Backlight String combined of 2 parallel of 28 serial LEDs(2 * 28 = 56 LEDs) My LED Driver Chip is...

    How to set MSP430 Driver Library timerA configurations

    I am using MSP430F5529 and MSP430 Driver Library. As you can see, I set upMode timer configuration, compare mode configuration and enabled the initial interrupts. However, timerA interrupt is not working, I set an indicator whether cod jumps into interrupt or not: ucsFault should be different...

    [SOLVED] Xilinx ISE ERROR:Xst:2369 - Empty project file "C:\xxxx" what is it about?

    Re: Xilinx ISE ERROR:Xst:2369 - Empty project file "C:\xxxx" what is it about? I created new project and it worked, I must have missed that part. Thanks a lot! But can you please tell me what part of the code would be better? I can use good critisism. Thanks.

    [SOLVED] Xilinx ISE ERROR:Xst:2369 - Empty project file "C:\xxxx" what is it about?

    I am trying to see the schematic output of my verilog module in Xilinx ISE. However, I am getting this silly error: I ve already tried restarting both ISE and computer but they did not help. So I am asking for help from experienced FPGAdevelopers. Here the top module I want to sythesize...

    [SOLVED] Verilog: What is the proper way to write a test module?

    Thanks for such detailed answer. But I thought that I initialized sck in the line: initial begin clk_divider [3:0] = 4'b0; tx_counter [3:0] = 4'b0; rx_counter [3:0] = 4'b0; cs = 1; sck = 0; end does not that cover it? Also, to make a hardware counter is this the way...
