摘要
The power supply has a full wave bridge (3) rectifier connected to the a.c. system (1) through a transformer and choke (2, 6). The d.c. output is chopped (4) and filtered (5) before being fed to the load. The chopper has a gate turn off device (10) programmed to chop the rectifier output to give a sinusoidal component of twice system frequency and a d.c. component. The filter (5) is tuned to twice system frequency. Operating at double frequency compensates for the naturally occurring harmonic in an idealised conventional system and thus enables unit power factor operation.
