  1. Ns, Nc, Nd, and NBD denote number of switches, switched capacitors, diodes, and bidirectional switches, TSV and MVS stand for the total standing voltage and the maximum voltage stress, PF stands for the power factor, C denote the capacitance values, fs stands for the switching frequency, THD stands for the total harmonic distortion and ηm stands for the efficiency.
