Hi, Please read and understand the project requirements before putting an offer. I need a circuit that takes 110V AC (or 220AC) and creates a burst width modulating power source for me. I need to be able to control all the parameters shown in the attached graph. Background info: - Full H-bridge circuit can do this Specifications: - Required power output: 100 Watts per circuit/PCB (or more) - Frequency range: 20-200 kHz - Resolution of the control for frequency: +/- 0.5 kHz - The conversion efficiency >85% is needed - Being able to control or program the circuit - Having a display is a plus - Circuit box housing needs to be designed too Payment: - No payment will be made if the 4 working PCB circuits are not delivered to the customer in 3 weeks
