The switching angles can be obtained through solving a set of transcendental equations with the coefficients from the inverter output waveform Fourier series. The conventional algorithm for resolving SHE-PWM problem is Newton-Raphson algorithm. The main shortcoming in applying Newton-type algorithms is that the results deeply depend on the selection of initial values. In this paper, a new algorithm is proposed to solve the nonlinear system in the SHE-PWM problem without suffering from above shortcoming. The algorithm first transforms the nonlinear equations into a polynomial problem. An important observation is that the original system and thus the polynomial are highly illconditioned, so the conventional algorithms can seldom accurately computing roots for the polynomial. A novel Eigensolve algorithm is introduced since the algorithm is especially good for solving the highly illconditioned polynomial. The simulation results indicate the robustness of the method.","PeriodicalId":406398,"journal":{"name":"2004 11th International Conference on Harmonics and Quality of Power (IEEE Cat.

To reduce such harmonics, active power filters (APF) are commonly employed. Where as shunt APFs are used for current-type load, series APFs are applied to voltage-type load and allow both voltage and current harmonic compensation. A new constant-frequency control scheme for a series APF is designed. The elaboration of the control law is based on a small-signal averaged model of the converter, computed in the (d,q) synchronous frame. The control scheme consists of two successive loops: the inner loop that ensure voltage harmonic compensation at the AC side is designed on the basis of the linear decoupling principle, whereas the outer loop that uses a simple PI controller ensures voltage regulation at the DC side of the filter. The control system is implemented numerically using Matlab/Simulink tool. The performance of the proposed control approach is finally discussed through the obtained simulation results.","PeriodicalId":406398,"journal":{"name":"2004 11th International Conference on Harmonics and Quality of Power (IEEE Cat.
