3. Temporary storage in supercapacitors
3.1 Inductive storage chopper
This type of chopper (figure 9a ) serves as a reference for the capacitive storage chopper. Energy is temporarily stored in a coil before being released to the load.
Consider figure 9c. Let's denote by α the duty cycle and TH the chopper period. During time α TH, voltage VL across inductance coil L is subjected to voltage Vs = 60 V. And during the time (1 – α ) TH, the voltage VL across the coil is subjected to the voltage Vu = – 20 V.
In fact, the variation in magnetic flux is :
