Different methodologies in choosing suitable values of the components, both inductor and capacitor, are presented for different objectives. The first two present a procedure to design the inductor limiting the current ripple of the filter. The others deal with the capacitor design: the first solution is based on the knowledge of the load spectrum, while the second one regards the worst load case for a given maximum current of the inverter switches. Both the algorithms are based on a model inversion and are control-oriented.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

The small signal models of both converters are first transformed into discrete-time models using the matched pole-zero mapping method. Digital controllers are designed based on the discrete-time model using the root locus method. By selecting the poles, zeros and gain of the digital controllers, the closed-loop poles are placed at desired locations in the z-plane. The digital controllers are then implemented on a TI DSP. The root locus design method is compared with the frequency response design method. Experimental results from the buck converter indicate that the results obtained using the root locus method are comparable to the results obtained using the frequency response method, while results from the boost converter indicate the nonlinear nature of the boost converter small signal model may degrade the performance of the design using the root locus method.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

The proposed control scheme can minimize the source current harmonics under the given active filter capacity, which can be realized by adjusting the magnitude and phase of the compensation current using the complex compensation gains in the frequency domain. The effectiveness of the proposed control scheme has been verified by experiments. As a result, the good effect on the compensation for the source harmonic currents in the proposed control scheme is obtained compared with that in the conventional one.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

The most common stepper motor controllers have all the elements to perform a microstepping control requiring only the digital control for the current level and direction in each winding. In this design we propose a cost-effective solution to integrate this control into high speed FPGA based designs. The core uses an FPGA block RAM to save conventional logic resources. Also, if the system needs to change the microstepping control granularity while the system is running, a partial dynamic reconfiguration can be performed only by changing the content of the block RAM attached to the core.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.
