SB is turned on at point t5. The SB switching loss can be minimized by turning on SB when the SB both-side
voltages are at a minimum (when the resonance voltage is at a peak). The SB turn-on timing can be set with TD1 of
the HA16163. The time when the resonance voltage is at a peak is given by equation (4).
From t5 onward, operation is on the same principle as in Subinterval 1 through Subinterval 5.
