Stepdownstepup
Stepdownstepup is a term used in power electronics to describe DC-DC converter topologies capable of both stepping voltage down and stepping it up, enabling bidirectional voltage regulation and energy transfer. The concept is most commonly associated with buck-boost and other bidirectional regulators that can adapt to varying input and output requirements.
Operation and topology: In these devices, operation falls into buck mode when the output voltage is lower
Design and performance considerations: Key factors include efficiency across operating ranges, control loop stability, and stress
Applications: Stepdownstepup devices are used in portable and battery-powered electronics, electric vehicles, renewable-energy interfaces, uninterruptible power
