Abstract: This paper presents a novel soft-switching boost DC-DC converter, which uses an
edge-resonant switch capacitor based on the pulse width modulation PWM technique. These
converters have high gain voltage due to coupled inductors, which work as a transformer, while
the boost converter works as a resonant inductor. Upon turning on, the studied soft switching
circuit works at zero-current soft switching (ZCS), and upon turning o, it works at zero-voltage
soft switching (ZVS) while using active semiconductor switches. High eciency and low losses
are obtained while using soft switching and auxiliary edge resonance to get a high step-up voltage
ratio. A prototype model is implemented in the Power Electronics Laboratory, Assiut University,
Egypt. Seventy-two-panel PV modules of 250 W each were used to simulate and execute the setup to
examine the proposed boost converter.
