I need help building a charging system for a motorcycle that has been converted to a 12v DC EFI system (formerly carbureted with a CDI ignition). The original full wave system was designed specifically to produce high voltage for the ignition system (32 gauge wire with thousands of turns). ...
The power supply generates 3 kV square-wave voltage pulses across the water treatment chamber at a frequency of 17 kHz. A 320 V DC bus is created from the 240 V AC input power source across two capacitors by using a bridge rectifier. The two IGBTs chop the DC bus voltage at 17 kHz ...
Full-Wave Antenna: Solving the Homework Homework Statement Homework Equations see attached imageThe Attempt at a Solution I'm not sure where to begin with this one. We did a similar problem with a half-wave antenna, where I=I_0 cos(2πz/λ) and it was centered at the origin, so cos...
