四开关Buck-Boost变换器的最小RMS电流波形编程控制

This article proposes a waveform programming control strategy for the four switch Buck–Boost converter. By adopting the quadrilateral inductor current modulation method, the degree of freedom is optimized, thereby enhancing the control accuracy. Zero-voltage switching is achieved within a wide input voltage and load range. Without changing the modulation mode, smooth switching between Boost and Bu...
