Stability improvement of pulse power supply with dual-inductance active storage unit using hysteresis current control

TL;DR

A hysteresis current control (HCC) scheme for dual-inductance active storage units that eliminates output current spikes and keeps the bus voltage smooth and stable in pulsed power supplies.

Key contributions:

• A small-signal model of the dual-inductance active storage unit under HCC, showing superior compensation performance over conventional current-mode control.
• A valley-voltage loop that regulates the storage-capacitor voltage, reducing power loss at any pulse duty cycle.
• Experimental prototype validation: current spikes effectively eliminated, stable bus voltage, and a significantly smaller output capacitor for the per-stage DC/DC converter.
