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 prolong battery life. |
