Abstract

This work investigates communication issues in
high-frequency power converters. A novel control
communication network (Power Electronics System
Network or PES Net) is proposed for modular,
medium and high-power, converters. The network
protocol, hardware and software are designed and
implemented. The PES Net runs at 125 Mb/s over
plastic optical fiber allowing converter switching
frequencies in excess of 100 kHz. Communication
control is implemented in a field programmable
gate array device. A novel synchronization method
applicable to ring networks is proposed. The
effect of the communication delay on the power
converter operation is studied.
