提出了一种基于四桥臂逆变器的三相无变压器UPS高性能输出电压控制方法。该方法采用电压控制回路，基频和谐波分量采用固定框架谐振滤波控制器。电容电流反馈回路提供了主动阻尼，提高了输出电压的动态性能，给出了控制器的设计和实现细节。考虑了平衡和不平衡负载工况下的线性和非线性负载。详细研究了UPS的稳态和动态性能。提出并实现了一种简单高效的标量PWM方法，通过理论、仿真和实验验证了控制和PWM方法的有效性。
A method for high performance outputvoltage control of a four-leg inverter based three-phase transformerless UPS isproposed. Voltage control loop is employed and the method employs stationaryframe resonant filter controllers for the fundamental and harmonic frequencycomponents. A capacitor current feedback loop provides active damping andenhances the output voltage dynamic performance. The controller design andimplementation details are given. Linear and nonlinear loads for balanced andunbalanced load operating conditions are considered. The steady state anddynamic performance of the UPS are investigated in detail. A scalar PWM methodwith implementation simplicity and high performance is proposed andimplemented. The control and PWM methods are proven by means of theory,simulations, and experiments.
