Beschreibung

The STDES-3KWTLCP is a 3 kW AC-DC converter designed for telecom rectifier applications. This type of application requires a high efficiency over the entire load range of operation and across the universal mains input voltage range.This reference design opens the path to a compact solution (up to 40 W/inch3), offering a high peak efficiency (96.3%), low THD distortion (less than 5% THD at full load), and a reduced bill of materials.The system consists of two power stages: a bridgeless totem-pole PFC controlled by an STM32G474RBT6 and an isolating regulation stage implemented with a full-bridge LLC with zero-voltage-switching (ZVS) PWM, and synchronous rectification (SR) controlled by a second STM32G474RBT6 microcontroller.The STDES-3KWTLCP also helps you to design an innovative topology with the latest ST power kit devices: silicon carbide MOSFETs, high-voltage MDmesh MOSFETs, STripFET MOSFETs, isolated FET drivers, and a VIPer converter.The STDES-3KWTLCP is a fully assembled kit developed for performance evaluation only, not available for sale.
