DC TO DC CONVERTER WITH FEED FORWARD AND FEED BACK REGULATION |
摘要 |
The invention provides a DC to DC converter capable of operating from a power source whose output voltage may change over a 10 to 1 range. A switching transistor (52) is used to convert the DC input voltage into a pulsed voltage. Feed forward control techniques are used to rapidly compensate for changes in the amplitude of the input voltage. Feed back techniques are used to maintain the output voltage at the desired value. Isolation between the input and output is provided using a transformer (50) to couple the switching circuits to a rectifier (92) and filter (94, 95) which produces the output voltage. A fiber optic link (153) provides isolation for the feed back signal. |
