摘要 为了对直流电压进行变换,采用DC-DC技术,设计输出电压可调的直流电压变换器。变换器包括驱动式方波电路、功率管组成的调整电路、比较采样电路和滤波电路。在multisim软件环境下进行仿真,并在实际电路进行测试,获得的结果满足设计要求。实验证明,升压变换器可实现输入5 V直流电压,输出12 V直流电压;降压变换器可实现输入12 V直流电压,输出5 V直流电压;具有良好的直流变换功能。 In order to transform DC voltage,DC-DC technology is used to design a DC voltage converter to accomplish adjustable DC voltage.The converter includes a square wave driven circuit,an adjustment circuit consists of power tubes,a sampling compared circuit and filter circuit.Under simulation by multisim and test in actual circuit,the result of test meets requirements.Experiments show that step-up converter can achieve 5V DC input voltage,output 12V DC voltage;Set-down converter can achieve input DC voltage 12V,output 5V DC voltage,the design has a good conversion function.
