    I'm on the lookout for a skilled and experienced circuit designer who can create a pulse charging circuit for a 12V or 24V battery. This circuit will need to be compatible with a 500watt, 44V, 12 A max solar panel. Ideally, you should be proficient in: - Designing circuits with a Pulse Width Modulation (PWM) generator - Building circuits that trigger a Mosfet, IGBT, BJT, or an equally efficient transistor - Engineering circuits with a charging voltage exceeding 100V - Regulating frequencies in the range of 0-10kHz. - Efficiency is crucial here. Don't want too much wasted energy in heat or heat dissipation, or waste half of the energy if it is 50% duty cycle. This is an opportunity to demonstrate your in-depth knowledge in electronics and circuit design. A robust understanding a...
