A pulse load averaging power converter (10) provides low duty cycle, high amplitude power pulses while drawing substantially constant power from a power source. A voltage peak detector (70) provides a pulse width modulator PWM (20) with a feedback signal proportional to the peak of the output voltage. A regulated switching power converter (200) utilizes pulse load averaging power converter (10). The resulting power converter provides high current, low duty cycle power pulses while, maintaining a substantially constant current draw on a battery (230). An individual subscriber unit (400) which operates in a cellular communications system utilizes, pulse load averaging power converter (10) to …

Why it's free to use
- Filed April 17, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 17, 2018.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
