multi-channel waveform generator for radar -preliminary design review

Preliminary Design ReviewWind Turbine with GearboxTeam GNick Koerner (Lead), Meteb Almutairi, Chris Batsch, Mike Villamar

System Design

Overview● Convert mechanical energy to electrical energy

while maintaining high efficiency● Maintain control to obtain maximum power

outputo Maintain a constant 5 V supply

● Durabilityo Avoid components maximum ratings

● Upon completion of assembled project, data can be gathered to produce the power curve performance graph
