Abstract: A DC-DC switched inductor boost converter with reduced switch voltage stress including two inductors and two active switches. The two inductors may be configured to charge in parallel when the two active switches are turned on, and the two inductors may be configured to discharge in series when the two active switches are turned off A Switched Inductor Boost (SI-B) converter is proposed with reduced voltage stress across active switches to achieve higher output voltage. The SI-B converter configuration is transformer-less and derived by replacing the diode of the classical switched inductor structure with an active switch. As a result, compared to the existing transformer-less high step-up converter or switched inductor boost converter, certain embodiments have the merit that the switch voltage stress across the active switch is less than the output voltage.
