—A hybrid cascaded multilevel inverter with PWM method is presented in this paper. It consists of a standard 3-leg inverter (one leg for each phase) and H-bridge in series with each inverter leg. It can use only a single DC power source to supply a standard 3-leg inverter along with three full H-bridges supplied by capacitors. Multilevel carrier-based PWM(More)

The half bridge modular converter configuration is used to perform the charging pulses with both positive and negative pulse. The positive pulse charge permits the high peak current charge which leads to quick charging mode. The negative pulse and idle state can offer low battery temperature rise. The frequency used for pulse charge technique can be varied(More)
