Power supply with increased dynamic range |
摘要 |
A power supply circuit impresses a signal supplied by a pulse generator (28) at one frequency on an alternating current such as a standard AC signal at 115 volts RMS and 60 hertz by utilizing a single switching transistor (Q1) coupled between the pulse generator (28) and a current-directing element (14) which, in turn, is serially coupled between a source (10) of the alternating current and a load (18). The resultant bidirectional output voltage across the load (18) may be rectified and averaged to produce a substantially constant DC voltage whose level is regulatable by controlling the duty cycle of the pulse generator (28).
