DC Voltage Conversion Circuit Using Opposite Phase Signals

The patent divides the voltage conversion process into multiple stages by introducing intermediate voltage nodes (first intermediate voltage node and second intermediate voltage node) between the input and output. Each stage uses capacitors and diodes to progressively boost the voltage, allowing the circuit to achieve higher output voltage and faster response while maintaining a relatively simple structure through modular segmentation of the conversion process.

The patent employs preliminary charging actions during the first half-cycle of the voltage-transforming signal, where capacitors C1 and C3 are charged to intermediate voltages in preparation for the final voltage boost. This preliminary action allows the circuit to complete the full voltage conversion in just one complete cycle of the voltage-transforming signal, doubling the productivity compared to conventional circuits that require two cycles.

The patent applies local quality by assigning specific functions to specific components at specific locations in the circuit. For example, capacitors C1 and C3 are strategically positioned to charge to intermediate voltages during the first half-cycle, while capacitors C2 and C4 handle the final voltage boosting during the second half-cycle. This localized functional assignment maximizes driving capability with a minimal number of components, avoiding unnecessary complexity.
