Voltage Equalizer for Two Batteries with Buck/ Boost Converters

Abstract

In this article is presented a complete schematic circuit of the power section and the control system for a voltage equalizer of two batteries. The equalizer consists of two buck/boost inverting DC-DC converters with common inductance. The operation of the circuit is described, and the computer investigation results, and practical use are presented. The shown and implemented device can find
application in systems with energy conversion from renewable sources and in electric vehicles.
