A novel double-input pulsewidth-modulation (PWM) dc/dc converter for high-/low-voltage sources is proposed in this paper. With a PWM control scheme, the can draw power from two different voltage simultaneously or individually. The operation modes and steady-state analysis of are introduced detail. scheme flow balancing also presented. By using single passive lossless soft-switching cell, switching losses all switches be reduced significantly. Finally, experimental measurements demonstrated...
Phase current is crucial for closed-loop control and system monitoring of a T-type three-level inverter (TThLI). However, the traditional space vector pulse width modulation (SVPWM) method cannot fully meet minimum sampling time, which leads to emergence unobservable areas (UAs) in neutral sensor (NCS) phase reconstruction TThLI. Moreover, zeropoint drift (ZPD) caused by temperature drift, aging, noise affects accuracy NCS sampling. Regarding issues above, this paper investigates impact UAs...
