6.5Line Transient

A line transient test was conducted with an ac source on the reference design. The line was varied from

230 VRMS to 115 VRMS to 230 VRMS and the transient response was evaluated in each case. From the oscilloscope image in Figure 19, it can be observed that the output recovered from line transients within 300ms at full load.
