Figure 29. Power vs frequency curve in an resonant half-bridge
As a result, the average input current will smoothly increase, without the peaking that occurs
with linear frequency sweep, and the output voltage will reach the regulated value with
almost no overshoot.
Typically, RSS and CSS will be selected based on the following relationships:
where fstart is recommended to be at least 4 times fmin. The proposed criterion for CSS is
quite empirical and is a compromise between an effective soft-start action and an effective
OCP (see next section). Please refer to the timing diagram of Figure 32 to see some
significant signals during the soft-start phase.
