A key issue for power electronic converters is the ability to tackle periodic signals in electrical power processing in such a way to precisely and flexibly convert and regulate electrical power.

This seminar is to provide complete analysis and synthesis of periodic control systems. It covers the control, compensation, and filtering of periodic signals in power electronic signal processing and proposes a unified framework for housing periodic control schemes for power converters, providing a general proportional-integral-derivative control solution to periodic signal compensation in extensive engineering applications – a perfect periodic control solution for power electronic conversion. This tutorial also consists of a number of demonstrative practical examples of the application of periodic control in: standalone Constant-Voltage-Constant-Frequency (CVCF) single-phase Pulse Width Modulation (PWM) inverters; standalone CVCF single-phase High-Frequency Link (HFL) inverters; standalone CVCF three-phase PWM inverters; grid-connected single-phase inverters; grid-connected single-phase “Cyclo-converter” type HFL rectifiers; grid-connected three-phase PWM inverters; programmable AC power sources; shunt active power filters; UPS systems; and synchronizations.

This tutorial is intended for researchers and engineers in the field of power electronics and their applications, for control specialists exploring new applications of control theory in power electronics, and for advanced university students in these fields.
