The conventional voltage source inverter is only a buck converter and conventional current source inverter is only a boost converter. By adding a Z-Source network, the buck-boost capability can be achieved. The recently proposed Quasi-Z-Source inverter (qZSI) is an important improvement to Z-Source inverter (ZSI), which greatly reduces the passive component stress. The current-fed qZSI can buck-boost...
Variable active passive reactance (VAPAR) is nonlinear time varying system which can generate virtual variable inductance including negative values in power circuits. AC source of VAPAR causes sinusoidal states in circuit then the circuit has not one fixed point in source period. And modified Poincare map must be used for modeling of these systems. The OGY method is used for controlling of chaos....
This paper presents an intelligent poultry stunner for improving carcass quality and animal welfare. In the stunner system, an active clamp circuit is used in a forward converter to reset the magnetizing energy and to recover leakage energy trapped in the transformer, increasing its conversion efficiency. In addition, a dither generator realized with a half-bridge inverter is adopted to fast breakdown...
