| Abstract |
This paper describes some specific problems encountered in a 2kW compact single-phase boost-type power factor conditioner suitable for telecom and navigation applications. Due to the required wide input voltage range (from 170V to 300V), a high nominal d.c. output voltage of 450V is required. This high voltage requirement puts considerable constraints on the choice of power components. Transient effects such as excessive diode reverse-recovery current and induced voltage spikes are also observed in the compact system in which power electronics are kept close to the low-voltage control electronics. Measures have been developped to suppress these transient effects to satisfactory levels. Experimental results with and without such measures are included and discussed. |
