Target applications include Welding, UPS, and Solar. In the topologies at the bottom of the slide shown here, one can see that the TS5 fits for the boost PFC in all three applications. It fits for an inverter stage in UPS and hard switching and resonant topologies in Solar. Looking on the right-hand side illustrates a Full Bridge Zero voltage switching topology, which is a resonant topology, meaning very low switching losses and furthermore it is a topology which reduces power losses (improves efficiency).
