摘要：建立了Z 源逆变器光伏并网系统的小信号模型，定量分析了光伏模块输出电压动态性能与主电路各参数间的
关系。光伏模块输出电压的最大功率点跟踪（MPPT）控制与系统采样平均周期关系密切，而采样平均周期又受主电路
无源元件参数大小的影响。定量分析小信号模型建立了各部分之间的传递函数，这对选择MPPT 控制采样平均周期
和主电路参数优化设计起到了关键性指导作用。实验证明了理论分析的正确性和该模型的实用性。

Abstract：This paper focus on the small-signal modeling of the Z-source inverter （ZSI） photovoltaic generation system and
its main circuit design.The small-signal modeling of ZSI photovoltaic generation system is set up，and the transfer functions
of the input voltage-to-shoot-through duty cycle and capacitor voltage-to-control are analyzed.The sample average period
plays an important role in photovoltaic generation maximum power point tracking （MPPT） control，while it is influenced by
main circuit parameters including input capacitor，Z-source network capacitors and inductors.Thus，the quantitative
analysis in those parameters is the design guideline for the main circuit and sample average period.The experiment carried

Description: This circuit uses the AC6 block of SimPowerSystems™ library. It models a permanent magnet (PM) synchronous motor drive with a braking chopper for a 3HP motor.
The PM synchronous motor is fed by a PWM voltage source inverter, which is built using a Universal Bridge Block. The speed control loop uses a PI regulator to produce the flux and torque references for the vector control block. The vector control block computes the three reference motor line currents corresponding to the flux and torque references and then feeds the motor with these currents using a three-phase current regulator.
