High step-up DC–DC converters are essential in electric vehicle (EV) and photovoltaic (PV) applications, where low-voltage inputs must be efficiently boosted to higher levels. Conventional converters ...

Power supply circuits come in the form of voltage step-up (boost) or the more common step-down (buck) DC/DC converter. Many of today’s applications require multiple voltage rails to drive a variety of ...

This paper introduces a new single-phase non-isolated symmetric-bipolar buck-boost alternating current-alternating current (AC-AC) converter, along with its associated commutation method. The topology ...

This is a 5V to 12V DC-DC step-up (boost) converter circuitry that is especially ideal for the USB powered applications. First of all a USB port has two current supply modes. Before detecting the ...
