Lighting Electronic Power System Integration & Soft Switch DC-DC Converter Research

The traditional power electronics system for production process, professional and technical personnel design, assembly workers - application system. Therefore there are many problems, such as the non-standard components, design cycle is long, low cost. And lead many parasitic inductance, and hindered power electronic technology further developing hf. Therefore needed Power electronic Module integration IPEM Power Electronics IPEM questions (done) research and development, further realize the integration Power converters. [1]. Lighting by MH lights electronic power system and power electronic components, is a typical power electronic systems. The research results of representative and universality and practicality, power electronics system to study other problems related to the strong guidance.In this paper, the first chapter introduces the integration of power electronics research background, The international research and development situation, the classification and study of the issue of hot spots.The second chapter introduces the main technical process of Integrated Power Electronics Modules (IPEMs):based boards manufacture→SMT→Ultrasonic cleaning→advance test→packaging→appearance treatment→ultimate test and delivery.This topic 575W MH lights electronic power integration module in strict accordance with the process flow assembly manufacturing, production.The third chapter developed 575W MH lights lighting system integration prototype. Lighting integrated electronic power supply system by the PFC module, BUCK module, inverter module, auxiliary power supply and the composition of a small number of passive components .After the integration and power density greatly improved greatly reduce weight, cost is reduced greatlyIn order to improve the power integration module power density, the fourth chapter presents a new full soft switch DC - DC converter and design method. USES half-bridge converter topology structure, the circuit by linear inductance commutation branch Lx - Cx realize switch tube T1, T2 of zero voltage open, Through the resonant branch L1 - C1 realize switch tube T1, T2 of zero voltage shutoff.
