H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system ...

Several power supply topologies, including SEPIC and flyback converters [1], generate a non-isolated, positive DC voltage from a positive DC input voltage range that extends both above and below the ...

A buck-boost converter maintains a regulated VOUT regardless of whether VIN is above, below, or equal to the output voltage. Ideally, the change from buck to boost and vice versa takes place ...

The most common switching-power topology is a buck converter, which efficiently transforms high voltages to low voltages. Figure 1 shows a typical buck converter in which the N-channel MOSFET, Q 1, ...

A high-efficiency buck-boost DC-DC converter was developed by the research team headed by Prof. CHENG Lin from the School of Microelectronics at the University of Science and Technology of China (USTC ...
