Temporary storage in supercapacitors
Ultracapacitors and power electronic systems

This type of chopper (figure 9 a ) serves as a reference for the capacitive storage chopper. Energy is temporarily stored in a coil before being released to the load.

Consider figure 9 c. Let's denote by α the duty cycle and T _H the chopper period. During time α T _H , voltage V _L across inductance coil L is subjected to voltage V _s = 60 V. And during the time (1 – α ) T _...
