Title:
LLC RESONANCE CONVERTER OUTPUT VOLTAGE SENSING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/145696
Kind Code:
A1
Abstract:
The present invention relates to an LLC resonance converter output voltage sensing method. The method according to the present invention comprises the steps of: detecting a time point at which a voltage applied to a secondary leakage inductor of a transformer is 0V; and at the time point at which the voltage applied to the secondary leakage inductor of the transformer is 0V, calculating an output voltage of an LLC resonance converter by using a first voltage measured at a point of contact between a resonance capacitor and a primary coil and a second voltage measured at a point of contact between a resonance inductor and the primary coil.
