Necesito el diseño completo de la tarjeta para un convertidor back-to-back AC-DC-AC con entrada trifásica y salida monofásica. El equipo deberá manejar aproximadamente 300 W con variaciones en la tensión de entrada, por lo que es importante cuidar el dimensionamiento de los semiconductores, el filtrado EMC y la gestión térmica. Qué espero recibir • Esquema eléctrico detallado con todos los valores y referencias. • Diseño de PCB listo para fabricación (archivos Gerber, taladros y pick-and-place). • Lista de materiales (BOM) con componentes disponibles en el mercado local o grandes distribuidores. • Notas de diseño que incluyan cálculo de filtros, estrategia de control y recomendaciones de disipación. • Opcional: archivos de simulación o modelos SPICE que faciliten la validación previa. Requisitos técnicos clave – Topología AC-DC-AC back-to-back. – Entrada trifásica AC variable, alrededor de 300 W de potencia. – Salida monofásica estable y protegida. – Factor de potencia y eficiencia competitivos. – Aislamiento y claras zonas de seguridad según normas industriales. Acepto propuestas en Altium Designer, KiCad o herramientas similares, siempre que los archivos fuente queden incluidos. Valorizaré experiencia previa en convertidores de potencia y ejemplos de trabajos relacionados.

Hi, When I saw your request for a PCB design for an AC-DC-AC back-to-back converter, it reminded me of several power electronics projects I’ve designed that combine efficient energy conversion, robust thermal management, and compact PCB layouts for high-reliability operation. These included three-phase AC-DC converters, isolated power supplies, and motor drive control boards with careful EMC filtering and semiconductor sizing. ✅ I have 11 years of extensive experience designing embedded and power electronics hardware, including AC-DC and DC-AC converters, thermal and EMC considerations, and end-to-end prototype-to-manufacturing development. ✅ I am familiar with full project workflows: schematic capture, PCB layout, BOM optimization, and preparing production-ready files with clear documentation. Before I outline a full approach, may I clarify: 1. What is the input voltage range and frequency for the three-phase AC? 2. Are there PCB size or layer constraints? 3. Are there target efficiency or THD levels for the AC output? Two quick suggestions: ✅ Prioritize clear separation between high-voltage and low-voltage zones with proper creepage and clearance. ✅ Include thermal vias and copper planes for reliable heat dissipation in high-power components. Freelancer doesn’t let me message first—please feel free to reach out, and I’d be happy to help deliver a robust, manufacturable AC-DC-AC converter PCB. Kind regards, Avi Gupta Quality is never an accident
