摘　　要：为了减小水下直流恒流供电中的功率限制,论文对一种能够使输出电流大于输入电流的新型电流/电压转换电路进行了建模和分析。由稳态关系知该电路能够通过调节控制脉冲占空比使输出电流大于输入电流。通过分析其传递函数可知该电路能够在物理上实现,且在输入电流或占空比受到扰动的情况下能够在较短的时间内达到稳定。In order to reduce the power limitation of underwater DC constant-current supply,a new type of current/voltage conversion circuit,which can make the output current greater than the input current,is modeled and analyzed.The steady state rela⁃tionship shows that the circuit can make the output current greater than the input current by adjusting the duty cycle of the control pulse.By analyzing the transfer function,it is known that the circuit can be physically realized,and can be stable in a short time when the input current or duty cycle is disturbed.
