| Abstract |
Current Source Recifiers among other alternatives, offer several advantages over line conmutated rectifiers. Advantages include displacement power factor control and reduced line current harmonic distortion. This paper analyses the current source rectifier (CSR) in transient and steady state, the models are developed in a synchronous reference frame. The load behavior is characterized for two load conditions, resistive load, or in general, increasing current for increasing voltage, and constant output power, decreasing output current for increasing voltage. Constant power operation can occur for a converter system supplying a PWM inverter with high dynamics. Several static converter characteristics such as power factor and real and reactive power are analyzed for both types of load. Transient characteristics are analyzed for both types of load by exact small-signal model with full set of equations. |
