Inverter jobs

I'm looking for a Particle Swarm Optimisation (PSO) based PI Inverter Controller for a Grid Connected Photovoltaic (PV) System. The inverter controller should be PI based as it will be more efficient in terms of cost and performance compared to PLL and Fuzzy Logic based controllers. This PSO-based PI Inverter Controller will be used to optimise the maximum power point tracking of the PV system and thus allow the system to make efficient use of the solar energy provided by the PV system. It will also ensure the safe and efficient conversion of the produced electricity from the PV system into suitable loads or electrical appliances. The controller should be able to handle any kind of environment condition as it will be used in very diverse locations for different ki...

20kW hybrid inverter, 20kWh batt, 25kW solar array, 60kW EV charger design for a site. I need this done quite urgently.

Looking for someone with a lot of knowledge in transformerless inverter. We are looking to create an auxiliary power either from the HV or LV of a transformer. So we are wanting to step down 480v to 20v 3 phase to power some systems. Must have a lot of experience and some starting project to share about this kind of work.

These are the project condition you have to done 1)you have two different inverter and battery 2)let first one is A and second is B 3)you should connect to same application 4)when A's battery less than 30 percent,then the application should automatically run by B also when B is low then automatically run by A

Greetings! I am looking for a skilled freelancer with expertise in MATLAB simulation to do a project titled "Development of Single-Phase Transformer-less DC-AC Inverter for Photovoltaic System". the task will involve: 1-Developing a MATLAB simulation utilizing Sliding Mode Control (SMC) to minimize switching losses within the system. 2-Creating a MATLAB simulation that employs hybrid Pulse Width Modulation (PWM) techniques to reduce leakage current. Please note that only the MATLAB solution is required for this project. If you possess the necessary skills and experience in MATLAB simulations, kindly submit your proposal along with relevant examples of your previous work. I look forward to collaborating with you on this project.

... and I'd like some ecommerce features to be included as well. This website should be modern, professional, and optimized for different devices. If you have the experience and know-how to create this kind of website, I look forward to hearing from you. I need a home/landing page along with a single shop page that allows customers to built their own kit, using a combination of solar panels, an inverter, the cabling and connectors and then the option to add a storage battery and a mounting system. It needs to be super fast and easy to use. It then needs to generate a lead/customer capture and email this through to us for completion. So no actual shop/online payments but this must be able to be added later. The whole look and feel needs to be 'warehouse' and all des...

We are looking for someone with experience in building transformer base 3 phase inverter. We are having issues where mosfets are burning. We built a buffer board using CD4011 ic to split the driver signal into 6 channels which is 3 for the high side and 3 for the low side. Then we built a transistor board and an optocoupler board that is used to feed the signal to the driver board which was designed using IR2110 ICs. This driver board is what should drive the emulator board (the mosfets) which receives the battery input and then drives the transformer. Currently the mosfets keeps getting hot and burning

Off grid solar station with an inverter connected to an external 3-pin socket need to track how many kWh's are discharged via the plug. Current thinking is tis might be a raspberry pi with a cellular modem, ideally connected to a clamp meter or similar Data sent to an IP address that can be accessed remotely in Excel or similar format. Does this sound achievable? If so, do you have any questions to be able to provide a quote. Ideal person is based in UK and able to help with hardware procurement and testing. Potential for future feature development Paul

I have a signal coming from 3 phase inverter, this signal has noise, I need to cancel the noise or suppress the common mode current to a value around 0.1A to 1A . We need to use active noise canceller (ANC) to suppress the Common Mode Current (CMC) to values less than 0.1A to 1A with small frequency. We need to use only active components which shouldn't be R, L, C, Transformer, etc... the output of the active noise canceller should be connected to Controlled Voltage Source, all the used blocks for the Active noise canceller should be compatible with C2000 library, as it will be programmed later on a microcontroller TMDSCNCD280049C which belongs to C2000 family, but this Programming in microcontroller is not in this task.

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 th...
