High power triboelectric nanogenerator based on printed circuit board (PCB) technology

Purpose – The purpose of this paper is to form copper coin-embedded printed circuit board (PCB) for high heat dissipation. Design/methodology/approach – Manufacturing optimization of copper coin-embedded PCB involved in the design and treatment of copper coin, resin flush removal and flatness control. Thermal simulation was used to investigate the effect of copper coin on heat dissipation of PCB products. Lead-free reflow soldering and thrust tests were used to characterize the reliable performance of copper coin-embedded PCB. Findings – The copper coin-embedded PCB had good agreement with resin flush removal and flatness control. Thermal simulation results indicated that copper coin could significantly enhance the heat-dissipation rate by means of a direct contact with the high-power integrated circuit chip. The copper coin-embedded PCB exhibited a reliable structure capable of withstanding high-temperature reflow soldering and high thrust testing. Originality/value – The use of a copper coin-embedded PCB could lead to higher heat dissipation for the stable performance of high-power electronic components. The copper coin-embedded method could have important potential for improving the design for heat dissipation in the PCB industry.

This paper presents a modified power factor correction (PFC) ON/OFF control and three-dimensional (3D) printed circuit board (PCB) design for a high-efficiency and high-power density onboard charger (OBC). By alternately operating one of two boost modules of the PFC stage at a 50% or less load condition, the proposed PFC control can reduce the load-independent power loss of the PFC stage, such as core loss and capacitor charging loss of switches. It enables OBCs to have high efficiency across a wide output power range and better thermal performance. The 3D-PCB design decouples a trade-off relationship of the PCB trace design and heat spreader design, increasing the power density of OBCs. A 3.3 kW prototype composed of an interleaved totem-pole bridgeless boost PFC converter and full-bridge (FB) LLC converter has been built and tested to verify the proposed PFC control and 3D-PCB effectiveness design. The prototype has 95.7% full power efficiency (98.2% PFC stage efficiency) and 52 W/in3 power density.

El cálculo del tamaño mínimo de un conductor eléctrico es siempre el primer punto de interés al momento de diseñar una tablilla eléctrica de alta potencia; en este artículo se presentan los factores considerados para calcular el tamaño del conductor, las fórmulas matemáticas utilizadas, la revisión del estado del arte y las reglas de conservación definidas para proteger los circuitos de una sobrecarga eléctrica; asimismo se presentan dos métodos para definir el tamaño del conductor, uno basado en estándares internacionales (método actual) y otro basado en supuestos de diseño que reducen las reglas de conservación para calcular el tamaño del conductor (método propuesto), además se presentan los resultados de las pruebas de validación y los análisis estadísticos que respaldan la implementación del método propuesto en el diseño de las tablillas eléctricas de alta potencia utilizadas en centrales eléctricas destinadas a la industria automotriz y que ofrece una reducción del 33% del contenido de cobre de las tablillas eléctricas de alta potencia en comparación con el método de diseño actual.
