| description | This paper introduces a control algorithm for soft-switching series LC converters. The conventional voltage-to-voltage controller is split into a master and a slave controller. The master controller implements constant current, constant voltage (CCCV) control, required for demanding applications, for example, lithium battery charging or laboratory power supplies. It defines the set-current for the open-loop current slave controller, which generates the pulse width modulation (PWM) parameters. The power supply achieves fast large-signal responses, e.g., from 5 <inline-formula> <math display="inline"> <semantics> <mi mathvariant="normal">V</mi> </semantics> </math> </inline-formula> to 24 <inline-formula> <math display="inline"> <semantics> <mi mathvariant="normal">V</mi> </semantics> </math> </inline-formula>, where 95% of the target value is reached in less than 400 <inline-formula> <math display="inline"> <semantics> <mi mathvariant="normal">s</mi> </semantics> </math> </inline-formula>. The design is evaluated extensively in simulation and on a prototype. A match between simulation and measurement is achieved. |
