Converting and controlling electric power using power electronic converters (PECs) have become essential stages in various industrial systems and processes. The operation of any PEC is achieved by generating signals to switch ON and OFF sets of solid-state switches, which are the main components of any PEC. Several switching methods (called modulation techniques) have been developed for operating and controlling PECs, among which are the pulse-width modulation (PWM), space vector modulation (SVM), and hysteresis-band current control (HBCC). Despite their abilities to operate PECs in various applications and adapt to different controllers, PWM, SVM, HBCC and other techniques suffered reduced magnitudes of their outputs and sensitivities to non-linear loads. As of late, a new modulation technique has been developed based on wavelet functions for operating single and three phase PECs. This new technique is called the wavelet modulation (WM) technique that has shown remarkable abilities to: i) improve the quality of outputs (reduced harmonic components), ii) increase magnitudes of desired output components, iii) maximize the energy transfer from the input side to the output side, iv) simplify the implementation (carrier signals and pre-defined switching patterns are not required), and v) improve the overall efficiency of PECs. This research project aims to develop and test a new family of controllers for single and three phase PECs operated by the WM, PWM, SVM, and HBCC techniques. The proposed family of controllers will be designed using the phaselet functions, which are capable of accurate, responsive, and simplified processing of signals with high distortions and non-linearities (similar to currents and voltages in PECs). The development of phaselet-based controllers will offer operating and controlling single and three phase AC-DC and DC-AC PECs to meet industry standards of high performance and efficiency, along with feasible implementation requirements. Such features can be key tools for improving performances of renewable energy systems, power supplies, micro grids, high performance motor drives, storage systems, electric and hybrid vehicles command and control, and other industrial applications.

使用电力电子转换器（佩奇）转换和控制电力已经成为各种工业系统和过程中的重要阶段。任何PEC的操作都是通过产生信号来接通和关断固态开关组来实现的，固态开关组是任何PEC的主要组件。已经开发了几种用于操作和控制佩奇的开关方法（称为调制技术），其中包括脉宽调制（PWM）、空间矢量调制（SVM）和宽带电流控制（HBCC）。尽管它们能够在各种应用中操作佩奇并适应不同的控制器，但PWM、SVM、HBCC和其他技术的输出幅度和对非线性负载的敏感性都有所降低。最近，基于小波函数的一种新的调制技术已经被开发用于操作单相和三相佩奇。这种新技术被称为小波调制（WM）技术，其显示出显著的能力：（一）提高产出质量（减少的谐波分量），ii）增加期望的输出分量的幅度，iii）最大化从输入侧到输出侧的能量传递，iv）简化实现（不需要载波信号和预定义的切换模式），以及v）提高佩奇的总体效率。本研究计划旨在开发及测试一系列新的控制器，适用于采用WM、PWM、SVM及HBCC技术的单相及三相佩奇。所提出的控制器系列将使用小相函数来设计，该小相函数能够准确、响应迅速且简化地处理具有高失真和非线性的信号（类似于佩奇中的电流和电压）。基于相线的控制器的开发将提供操作和控制单相和三相AC-DC和DC-AC佩奇，以满足高性能和效率的行业标准，沿着可行的实施要求。这些功能可以成为提高可再生能源系统、电源、微电网、高性能电机驱动器、存储系统、电动和混合动力汽车命令和控制以及其他工业应用性能的关键工具。
