摘要
针对当前绿色能源单独供电不稳定,而逆变并网技术要求高的情况下,采用直流辅助供电方法,设计了以电压型控制芯片TL494为电源管理芯片、DC/DC推挽变换器为主电路拓扑结构的脉宽可调制的开关电源,并给出了系统的电路设计方法以及主要功能模块电路的参数计算,同时对该电源进行了性能测试,搭建了直流辅助供电的硬件实验平台,并进行了可行性验证。实验数据和结果表明设计的可行性。
In view of the current green power supply instability alone and the demand of invert grid-connected technology is high,this paper adapts the dc auxiliary power supply method.Designed with the voltage type control chip TL494 as the core,DC/DC push-pull converter as main circuit topology of pulse width modulation switching power supply,the circuit design method of the system and the main function modules of the circuit parameters are calculated.At the same time,the performance of the power supply is tested,and the hardware experiment platform is built.Experimental data and results show the feasibility of the design.
