Title:
APPARATUS AND METHODS FOR SENSING RESONANT CIRCUIT SIGNALS TO ENHANCE CONTROL IN RESONANT CONVERTER
Document Type and Number:
Japanese Patent JP2020096519
Kind Code:
A
Abstract:
To provide a resonant converter capable of sensing resonant circuit signals to enhance control.SOLUTION: A resonant converter 100a includes a resonant transformer 107 having a leakage inductance Land a magnetizing inductance Lcoupled in series to form a resonant transformer input port. The resonant transformer has an output that is coupled to provide an output power to a load 113. A primary bridge circuit 103 is coupled to provide an input power to the resonant transformer input port. A buffer circuit 116 is coupled in parallel with the resonant transformer input port. A control module 70 is coupled to receive a buffered primary port signal from the buffer circuit to control the primary bridge circuit 103 to control the output power to the load in response to the buffered primary port signal.SELECTED DRAWING: Figure 1A
