提出了一种新型的直流-直流变换器，其升压比和降压比可以通过改变外部时钟来控制。这些转换器由开关电容器组成，这些开关电容器形成由MOSFET开关连接的环（“环型SC”）。该电路具有以下特点：（1）由于其对称结构，可以通过改变时钟模式来程控其升压比和降压比。(2)它们可以处理从低电压到高电压的宽输入电压范围，而无需改变它们的结构。(3)通过使用DIP开关或计算机控制，可以提供各种输出电压。(4)它们可以有助于降低生产成本，因为它们对应于同一电路的各种输入和输出电压。(5)可以容易地实现控制装置的软启动电路。(6)由于无线圈结构，磁场的产生极低，因此它们可以与其他信号处理电路（例如片上系统或包括电源的系统集成）一起以单芯片IC形式实现。© 1999 Scripta Technica，Electron Comm Jpn Pt 2，82（11）：14-27，1999
New dc–dc converters are presented whose step-up and step-down ratio can be controlled easily by changing their external clocks. These converters consist of switched capacitors that form a ring connected by MOSFET switches (“ring-type SC”). The proposed circuits have the following features: (1) Their step-up and step-down ratios can be controlled programmably by changing the patterns of clocks because of their symmetry structure. (2) They can treat a wide input voltage range from low voltage to high voltage without changing their structures. (3) Various output voltages can be supplied by using DIP-switches or a computer control. (4) They can contribute to lower the costs of production, since they correspond to various input and output voltages with the same circuit. (5) A soft start circuit of the control apparatus can be easily realized. (6) They can be implemented in one-chip IC form together with other signal processing circuits such as a system-on-chip or a system integration including power supplies, since generation of a magnetic field is extremely low due to the coilless construction. © 1999 Scripta Technica, Electron Comm Jpn Pt 2, 82(11): 14–27, 1999
