Abstract:
1. A high efficiency balancing of individual cells in a battery comprising: a power core; a control core; a gate driver driving the control core with a varying drive signal; at least first and second half-converters, each half-converter inductively coupled with the power core and with the control core, each half-converter comprising: a first winding disposed for inductive coupling with the power core, the first winding having at least a first tap and a second tap; a second winding disposed for inductive coupling with the control core, the second winding having at least a first tap and a second tap; a first terminal and a second terminal, the first terminal and the second terminal connected by at least one semiconductor switch with the first winding; the at least one semiconductor switch having a control terminal, the control terminal of the semiconductor coupled with the second winding.
