摘要: A new utility-to-DC, harmonic-free interface combines the functions of automatic input current shaping, fast output voltage regulation, and lossless, soft switching in a single power converter. This was made possible through internal energy storage discovery modes operation, which together, effectively decoupled boost-like part Cuk converter from its buck-like output. Experimental results obtained on 50 W-12 V prototype confirm regulation (30 kHz bandwidth for 100 frequency) simultaneously with low-harmonic line waveforms. >
