Abstract
Embodiments of the present invention relate to a low-output voltage converter, delivering voltage power less than 1 VDC, utilizing distributed secondary circuits. In one embodiment of the present invention, there is provided a voltage converter comprises a primary circuit for receiving an input voltage, comprising a plurality of primary windings arranged in series, a plurality of secondary circuits, each comprising a secondary winding for aligning with a primary winding to form a transformer, and each of the secondary circuits arranged in parallel, and an output for providing an output voltage down to, or less than 1 VDC.
Claims21
A voltage converter comprising:
- a primary circuit for receiving an input voltage, comprising a plurality of primary windings arranged in series;
- a plurality of secondary circuits, each comprising a secondary winding for aligning with a primary winding to form a transformer, and each of the secondary circuits arranged in parallel;
- and
- an output for providing an output voltage of down to, or less than, 1 VDC.
A voltage converter comprising:
- a primary circuit for receiving an input voltage of between about 150 VDC to about 400 VDC, or between about 250 VDC and about 700 VDC, the primary circuit comprising a plurality of primary windings arranged in series as well as a common switching regulator that feeds said windings;
- a plurality of secondary circuits arranged in parallel, each comprising a plurality of secondary windings for aligning with a plurality of primary windings to form a plurality of transformers, and each comprising a rectifier for converting an input AC voltage signal to an output DC voltage signal;
- and
- an output for providing an output voltage of less than or equal to 1 VDC.
A method for converting an AC power source to a low-voltage DC output:
- providing a power converter comprising:
- a circuit for receiving an AC input voltage and converting it to a non-galvanically isolated DC voltage, said voltage being delivered to a primary circuit, comprising a plurality of primary windings arranged in series, as well as a common switching regulator that feeds said windings;
- a plurality of secondary circuits arranged in parallel, each comprising a secondary winding for aligning with a primary winding to form a transformer, and each of the secondary circuits comprising a rectifier for converting an input AC voltage signal to an output DC voltage signal;
- and
- an output for providing an output voltage of less than or equal to 1 VDC;
- and
- supplying the input voltage to the primary circuit, the input voltage ranging between about 100 VAC and about 330 VAC, or between about 380 VAC and about 500 VAC.
