6.1 Ripple voltage of boost voltage
■
At low temperature, ripple voltage of boost voltage increases due to Cbc freezes.
■
Select a capacitor of which ripple voltage of boost voltage does not exceed 30Vp-p
on an actual operating condition.
And check the maximum allowable ripple current of the capacitor.
■
Fig.6.1 and Fig.6.2 shows the relationship between ripple voltage of boost voltage and
temperature(Vin=AC85V).
