Power Electronics & Battery Management (BMS) Jobs

I'm looking for a reliable DC power supply for my coil tattoo machine equipment. It needs to include a rechargeable lithium ion battery that will last running at 12 volts for a minimum of 13 hours. A 1/4” jack, a voltometer, an on off button, and a panel mounted voltometer at minimum. It needs to be as small as possible for ease of travel and obviously cordless unless charging. Thank you Requirements: - Type: DC power supply - Voltage: 12V - Current: 1A, 5A, or 10A (I'm unsure about the exact requirement) Ideal Skills and Experience: - Experience with power supply design and specifications - Knowledge of DC power supply units - Ability to provide recommendations for optimal current output Please provide a detailed proposal including your approach and any relevant experi...

I am looking for an experienced power electronics engineer or engineering team to design a residential-scale hybrid solar inverter for commercial production. The project involves developing a single-phase, 230 V AC, 50 Hz pure sine-wave hybrid inverter that integrates rooftop solar panels, a lithium battery bank and the utility grid. The design should prioritise high efficiency, reliability, safety and ease of manufacturing. I prefer an engineer with previous experience designing working solar inverters, grid-connected converters, MPPT controllers and bidirectional battery systems. An existing, validated reference design that can be licensed or transferred is preferred. 1. Target Specifications Rated power: 1–5 kW continuous AC output: 230 V RMS, single phase, 50 Hz Output wave...
