    DC to AC - conditioning device 6 días left
    VERIFICADO

    I need help with design of a device which can take DC (variable voltage as input from 12-60v) and convert that into an AC 110 volt 60 Hz (also 220 volt 50 Hz) and such device should be able to sense voltage and frequency of the grid , where we are trying to feed , and based on that, it can synchronize frequency and voltage. And then it can feed power to the grid, but say from usual household plug so that it becomes portable device for say uto 1000 Watt portable solar power generators, wind generator. If output voltage sensing is difficult then probably 2 models - 110volt 60 Hertz and 220volt 50 Hertz. Also need a prototype shipped to me to US, along with all the schematics, drawings, designs.

    I plan to use a TPS54283PWPR from Texas Instruments in a project I am working on. I need an experienced engineer to help design my schematic and to ensure I have not made any silly mistakes (before I commit to the PCB) - alternatively, if this proves to be the incorrect part I will need help to identify alternative. All I need is a reliable DC DC converter with 24vDC input and output 1 = 5v at about 2 amps and output 2 at 3.8v at about 1.5 amps (I'm struggling with the maths in the datasheet)

    I uploaded the MATLAB Simulink for 3 phase motor driven by 3 phase Inverter, and feeded by SPWM. I need MATLAB simulink for single phase motor which is driven by inverter, and the common mode voltage and the common mode current in this case should be suppressed, which means the common mode current should be around 0.1A and with small frequency. The stray inductance, capacitance and resistance should be used as given in the MATLAB file I shared, also the parameters for SPWM. For this u should use active noise cancellation, which means, that it's forbidden to use passive components like for example resistors, capacitors, or inductors. You should only use active components which can be used later to program a microcontroller, this microcontroller is TMDSCNCD280049C. All the Blocks which...

    I am currently developing a battery powered DC variable power supply and I need a PCB created to control it. I would need it to have a buck boost circuit that could do 0vdc-60vdc @5amps as well have a current limiting feature for testing equipment, etc. & perhaps digipots to control the output voltage and current limiting digitally through the menu. I also will be using a TFT LCD to display a menu & to show voltages & current draw, so using an STM32 to drive & control all the logic would be preferable. Im not sure which batteries would be best to use in this so achieve the desired power outputs that I want so perhaps you may have some suggestions for batteries but for whichever batteries it would need a BMS and all protections as well with a USB C recharging circuit for re...

    This project is based on ESP8285 microcontrollers and programming should be done in Visual Studio Code (PlatformIO) Background: This is supposed to be a monitoring system. It involves detecting sensor values at multiple locations (at least 25, with more to be added, on demand). Each sensor location is connected to an ESP8285 wifi board on UART1 (soft serial). All of the 25 individual wifi modules will connect to a central hub - which is another ESP8285 module. This central hub will be connected to a cloud server through a broadband router. It will send the data of all the 25 sensors to the cloud server. The cloud server will also reply back some data which needs to be transmitted back to the 25 sensor modules. Based on this data, the individual 25 sensors will perform some action, like ...

    I need help creating a custom DIY bark repellent device. It can be based on Arduino, Raspberry or pure electronics - Raspberry and Arduino being the best as they can be easily updated or programmed. Anything I can find on the market are small toys without the much required power. It has to use larger loudspeakers - not the tiny kind you see in any bark repellent It has to allow change of frequency (as in adjusting for a specific dog/animal). From what I understood it has to emit ultrasonics around 20kHz-25Khz (in case of dogs) so it is not a such complicated device but I need someone to think about all these aspects and compatibility of the electronic pieces.
