Project Title: Electrical Engineer – Design of Universal Duplex Pump Control Panel Project Overview: We are developing a standardized duplex pump control panel to be sold as a commercial product worldwide. The goal is to finalize professional electrical engineering drawings, schematics, and a build-ready package for a compact control panel that operates two 3-phase pumps up to 25HP. The panel must be designed as a universal platform that can operate at 208/230V or 460V using simple component changes (conversion kits), without redesigning the control system. This is a product-development project, not a one-time building job. ⸻ Scope of Work The electrical engineer will be responsible for producing a complete construction-ready design package based on ...
I need an engineer to take my concept for a high-voltage DC-DC converter and translate it into a complete, build-ready design that slots straight into a renewable-energy storage setup. The converter will accept 24 V DC at the input and deliver a regulated 165 V DC output. Efficiency, thermal management, and long-term reliability matter far more to me than squeezing every last cent out of the BOM, so component quality and sound topology choices come first. You will own the full electrical design flow—topology selection, key-component sizing, magnetics specification, control strategy, and all supporting calculations. I expect LTspice or an equivalent simulation environment to demonstrate stability, transient response, and efficiency before we move on to hardware. ...
