First Claim
Patent Images
1. A buck-boost alternating voltage regulator comprising:
- A. an alternating current winding;
B. a second alternating current winding;
C. a rectifier;
D. a center tap connecting the first mentioned winding with the rectifier;
E. an alternating current output conductor;
F. a power amplifier connected with the rectifier and the output conductor;
G. a conductor connecting the center tap with one end of the second mentioned winding;
H. an output conductor connecting the opposite end of the second mentioned winding;
I. a preamplifier;
J. a conductor connecting the second mentioned output conductor with the second mentioned amplifier;
K. a resistance in said last mentioned conductor;
L. a conductor connecting the first mentioned output conductor to the input end of the second mentioned amplifier through a second resistance;
M. a conductor directly connecting the output end of the second mentioned amplifier to the first mentioned amplifier, whereby the first mentioned power amplifier is connected in such a way that the alternating current line voltage appears only in the power supply circuit of the first mentioned power amplifier, and in such way that in order for line voltage disturbances to propagate to the output, such disturbances must first be attenuated by the power supply rejection ratio of the first mentioned power amplifier and then further attenuated by the feedback loop gain factor of the entire system.
