PRODUCTION DATA.
One of the simpler high-efficiency topologies connects the system load directly across the battery pack, as shown in Figure 33. The input voltage has been converted to a usable system voltage with good efficiency from the input. When the input power is on, it supplies the system load and charges the battery pack at the same time. When the input power is off, the battery pack powers the system directly.
