電力操作系統中高頻開關電源的并聯均流技術

摘要：隨著分布式電源系統的發展，高頻開關電源模塊逐漸取代了傳統的相控整流電源，而高可靠性、大功率高頻開關電源模塊的需求已逐漸形成一種趨勢。文中介紹了一種新型高頻開關電源及220V/10A整流模塊的實現方案。其中整流模塊采用高可靠性電流型PWM整流器及全橋變換電路來分別實現三相功率因數校正和DC/DC變換，并在模塊間采用最大電流自動均流法實現自主均流。 敘詞：高頻開關電源 電流型PWM 并聯 自主均流 模塊 Abstract：With the development of the distributed power system, the high-frequency switching power supply module gradually replaced the traditional phased rectifier, and the demand of high reliability, high-power high-frequency switching power supply module has gradually become a trend. This paper presents a new high frequency switch power supply and implementation of 220V/10A rectifier modular. The rectifier module implements the 3-phase power factor correction and DC/DC conversion using highly reliable main circuit topology, and implements the automatic current-sharing control using the maximum-current control method.
