Latest Patents

James J Campbell holds a patent for a "Precharging apparatus and power converter." This invention presents precharging systems and methods for precharging a DC bus circuit in a power conversion system. The system connects precharging current through a precharging resistance coupled between a single AC input line and the DC bus circuit when the DC bus voltage is less than a non-zero threshold. A controller activates controllable rectifier switching devices when the DC bus voltage is greater than or equal to the threshold. This is achieved using DC gating or pulse width modulation to selectively provide a bypass path around the precharging resistance for normal load currents in the power conversion system. He has 1 patent to his name.
