AI Technical Summary
Existing single-input multiple-output (SIMO) converters suffer from inefficiency and output oscillation issues in component selection and control, especially in electronic systems with varying DC voltage requirements. A more efficient DC-DC converter is needed to address these problems.
The switching converter topology employs a self-operated negative boost switch. By using laterally diffused metal-oxide-semiconductor (LDMOS) transistors and diode-connected P-type metal-oxide-semiconductor (PMOS) transistors, combined with a regulating circuit to maintain the control terminal voltage of the switch, it achieves an autonomously controlled negative boost mode, avoiding dependence on traditional controllers.
It improves the efficiency and stability of the converter, reduces output oscillation, enables efficient switching in electronic systems with different DC voltage requirements, and reduces energy loss.
