Can a high-frequency transformer isolate energy storage battery?
Compared with the conventional topology [22, 23], the energy-storage PCS proposed in this paper is isolated by a high-frequency transformer, which can cancel the power frequency transformer, reduce the volume of passive components, improve the power density of equipment, and reduce the insulation costs of energy storage battery.
Does a buck-boost circuit reduce battery life?
CHB is challenging to adapt to multiple types of energy storage batteries, and the double fundamental frequency fluctuation in the BESS will reduce the battery life [7, 8, 9]. The topology composed of an H-bridge and DC/DC converter, such as a non-isolated buck-boost circuit, can suppress the BESS’s double frequency power fluctuation.
