Power Electronics & Battery Management (BMS) Jobs

I’m building a small consumer-electronics project and need a purpose-built, rectangular PCB that can drive an induction heater at up to 100 W. The board must accept power from either a standard DC adapter or a USB-C PD or DC source, automatically negotiating or routing whichever is connected. Power control is intentionally simple: ten individual LEDs indicate output in 10 W increments (10 W – 100 W), and a single rotary dial steps the power up or down in those same 10 W stages. No screen, menus, or extras—just clean, reliable hardware. What I expect from you • Complete schematic with component values, coil connection, gate-drive stage, protection (over-current / over-temp), and USB-C PD or DC supply trigger circuitry. • PCB layout ready for fabrication...

PCB Design & Engineering for HydroNest RO Plant Controller 1. Project Objective We are developing a professional controller PCB for commercial/light-commercial RO water treatment plants under HydroNest India. The objective is to take our existing functional requirements, selected components/modules and control logic, and have an experienced electronics engineer design, optimize and finalize the complete electronic controller. We are not looking only for PCB layout work. The engineer should be capable of taking the requirements at a system level and developing the complete electrical design, schematic, component selection/optimization and production-ready PCB. ⸻ 2. What We Will Provide We will provide: * RO plant operating requirements and sequence * List of pumps, solenoid valv...
