Abstract

 Abstract— This paper proposes two kinds of new single-inductor dual-output (SIDO) DC-DC switching converters with ripple-based hysteretic control. First SIDO converters of type 1 utilize the triangular signal generated by the CR-circuit connected across the inductor. This triangular signal is used for generating the PWM signal instead of the saw-tooth signal used in the conventional converters. Second SIDO converters of type 2 utilize the triangular signal generated by the CR-circuit connected across the voltage error amplifier. This paper describes circuit topologies, operation principles, simulation results and experimental results of the proposed SIDO converters. In simulation results of both type of SIDO converters, static output voltage ripples are less than 5mVpp and over/under shoots of the dynamic load regulations for the output current step are less than +/10mV. In experimental results of single output converter of type 2, static output voltage ripples are about 20mVpp. Output ripples of SIDO type 1 converter are about 80mVpp.

具有滞回控制的高速响应单电感双输出DC-DC变换器

摘要-本文提出了两种基于纹波滞回控制的新型单电感双输出(SIDO) DC-DC开关变换器。第一类SIDO转换器利用连接在电感上的cr电路产生的三角信号。该三角信号用于产生PWM信号，而不是传统变换器中使用的锯齿信号。第二型SIDO转换器2利用连接在电压误差放大器上的cr电路产生的三角形信号。本文介绍了SIDO变换器的电路拓扑结构、工作原理、仿真结果和实验结果。在两种SIDO变换器的仿真结果中，静态输出电压纹波均小于5mVpp，输出电流阶跃的动态负载调控过/下跳均小于+/10mV。在2型单输出变换器的实验结果中，静态输出电压纹波约为20mVpp。SIDO 1型变换器的输出波纹约为80mVpp。
