Efficient Steady-State Simulation of Switching Power Converter Circuits
This paper presents a new approach aiming at simulating the steady-state response of DC-DC switching power converters. The proposed method uses the main concept behind the Harmonic Balance (HB) to compute the amplitudes of the harmonic content in the steady-state waveform. The proposed approach extends the basic HB to enable its efficient implementation to the power converter circuits, through developing equivalent frequency-domain-based stamps for ideal switching elements. The new technique is formulated to yield, along with the amplitudes of the harmonics, the switching times in the ideal switching elements, resulting in the convergence of the Newton method being obtained within few iterations. A major advantage in the proposed method is that it enables removing the control circuitry, which reduces the size of the circuit and significantly contributes to the efficiency of the method. Experimental results shows significant speedup over commercial SPICE-based simulators.
