A single pulse width modulation controller (PWM) is possible for the present invention for not only start-up but also normal boost modes. A primary circuit can have a clamping switch or at least two choke diodes. The choke diode can include “push-pull” and “L”-type configurations. A resistor can be used to dissipate energy clamped from the voltage spike. A startup circuit can be used to eliminate the in-rush current experienced during start-up. The proposed start-up schemes have been experimentally verified using a 1.6 kW, 12V/288 V prototype. Since the present invention eliminates the need to match characteristics of multiple controllers, it significantly reduces the cost associated with implementing this type of technology.application/pdfen-USPatenthttp://pimg-fpiw.uspto.gov/fdd/56/873/065/0.pdf9866304323/908363/17363/49363/56.2363/56.5H02M1/34H02M3/3376H02M2001/342Y02B70/1491Y10S323/9086587356
