A single-phase rectifier based on neutral-clamped converter (NPC) is proposed to achieve high power factor, lower current distortion and low voltage stress of power semiconductors. The principle of single-phase three-level PWM rectifier is introduced. Neutral-point balance problem is an inherent problem of three-level converter, so a bangbang control method is schemed to control the capacities' voltage...
Cascade inverter have become increasingly popular in recent years due to their practicability. This paper will present a novel composite cascade multilevel converter that is derived from these two topologies. The proposed converter structure is the series-connection of a five level diode-clamp converter and several three level H-bridge converters with equal dc bus voltage. Accordingly, for the novel...
Phase-shifted full-bridge zero-voltage switching PWM converters work in discontinuous current mode (DCM), when the current of output filter inductor is discontinuous in one switching period. The oscillation of inductance voltage is found in DCM converter. The operation principle in this mode is described in detail in the paper to research the oscillation phenomenon. Critical continuous condition is...
This paper proposed a novel hybrid cascade multilevel converter in which a Neutral-Point-Clamped (NPC) converter and several identical H-Bridge converters with equal dc bus voltage are series connected to form a converter phase leg. Accordingly, for the novel converter a hybrid modulation method which incorporates square-wave synthesis in conjunction with triangle carried-based PWM method is employed...
