Abstract：This paper mainly develops a novel topology，which is called quasi-Z-source inverter（QZSI），derived from the traditional
Z-source inverter（ZSI）.The equivalent circuit and operating principle analysis are given and the space-vector PWM
technique is applied into single phase QZSI（spQZSI），the basic modulation principle and control strategy of spQZSI based
SVPWM are showed.The simulation and experimental results indicate the presented QZSI has merits of suppress the inrush
current and remarkable lower component voltage ratings，thus save the entirety costs and strength the system reliabilities.

Description: 该仿真模型是一种利用模糊控制器调节PWM信号占空比的异步电动机直接转矩控制的策略，即在传统异步电动机直接转矩控制的基础上，用模糊控制器代替传统DTC中的滞环比较器和空间电压矢量状态选择器来细分控制规则，最后控制逆变器的开关，以减小转矩和磁链脉动，从而改善交流异步电机伺服系统的动、静态品质，使整个系统具有较强的鲁棒性和自适应性。-A method of the stator resistance estimate which based on the fuzzy neural network was proposed and the motor speed is estimated by MRAS speed identification algorithm based on the stator voltage and the current that can be easily detected. Besides, a new design of fuzzy direct torque control system of induction motor was introduced in this paper, which based on strategy of modulating the duty cycle to decrease the torque and stator flux ripple. This design uses fuzzy control block to instead of the traditional space voltage vector selector to control the inverter switch which can improve the static and dynamic performances of AC asynchronous motors, which make the whole control system have strong robustness.

Description: A method used to determine the harmonic components of the output waveform of a pulse width modulation (PWM)
inverter is presented. The method calculates the Fourier coefficients of individual positive and negative pulses of the
output PWM waveform and adds them together using the principle of superposition to calculate the Fourier coefficients
of the entire PWM output signal. This method allows direct calculation of harmonic magnitudes and angles without
having to use linear approximations, look-up tables, or Bessel functions. The method presented is a general method that
can easily be extended to various types of multilevel inverters and PWM schemes.-A general method used to conduct a harmonic analysis on carrier-based pulse width modulation inverters

Description: 采样控制理论中有一个重要结论:冲量相等而形状不同的窄脉冲加在具有惯性的环节上时,其效果基本相同.PWM控制技术就是以该结论为理论基础,对半导体开关器件的导通和关断进行控制,使输出端得到一系列幅值相等而宽度不相等的脉冲,用这些脉冲来代替正弦波或其他所需要的波形.按一定的规则对各脉冲的宽度进行调制,既可改变逆变电路输出电压的大小,也可改变输出频率.-Sampling control theory has an important conclusion: the impulse is equal but different shapes of narrow pulses added to the inertia of the link, the effect is basically the same. PWM control technique is to this conclusion based on the theory of the semiconductor switching device on and off to control the output side by a series of equal amplitude and pulse width are not equal, with these pulses instead of sine wave or other needs. according to certain rules of the pulse width modulation, can change The size of inverter output voltage can also change the output frequency.
