Abstract
A Single Input Dual Output converter includes a first switch coupling an input to a first inductor terminal, a second switch coupling a second inductor terminal to ground, a third switch coupling the second inductor terminal to a positive output, and a fourth switch coupling the first inductor terminal to a negative output. During time-shared control, the negative and positive outputs are independently served by conversion cycles. Each conversion cycle includes: a positive phase with a positive charge phase (closing only the first and second switches), followed by an additional phase (closing only the first and third switches for a given time duration), and followed by a positive discharge phase (closing only the third and fourth switches). Each conversion cycle further includes a negative phase with a negative charge phase (closing only the first and second switches) followed by a negative discharge phase (closing only the second and fourth switches).
