设计了一种超级电容器绝热充放电电路。微处理器设置控制电感电流的开关晶体管的占空比。以逐步方式改变占空比导致输出电压以类似方式改变。逐步电压变化使绝热充放电成为可能。目前的测量表明，超级电容器的八步充放电将能量耗散减少到恒压过程的八分之一。这种电路可以精确地以小步控制电压。
A circuit for adiabatically charging and discharging a supercapacitor was designed. A microprocessor sets the duty ratio of the switching transistors that control the inductor current. Changing the duty ratio in a stepwise fashion causes the output voltage to change in a similar fashion. Stepwise voltage changes enable adiabatic charging and discharging. Current measurements showed that the eight-step charging and discharging of a supercapacitor reduced the energy dissipation to one-eighth of that for a constant-voltage process. The circuit enables precise voltage control in small steps.
