020039: Z-Source Power Converter for High-Efficiency Power Conversion
Case ID:
TEC2002-0039
Web Published:
7/21/2014
Description:
Power converters, also known as power inverters,
are necessary components to all electrical/electronic products. Due to their
ubiquity, power converter attributes such as efficiency, robustness, cost, and
peak power are very important.
Description
The invention is an Impedance Source (Z-source)
Power Converter. The converter performs both buck and boost conversion, and one
of DC/DC, AC/DC, or AC/AC conversion.
This converter increases robustness
and efficiency while maintaining the desirable traits of prior converters (e.g.
V- and I- converters). It can be used for high power applications like electric
fuel cells and automobiles.
Benefits
- Increased
Robustness: The topology of the Impedance Source (or Z-Source) is immune
to EMI compared to standard V- and I- converters.
- Broader
Applicability: The output voltage of Impedance Source (Z-Source)
converter can be lower and higher than its input; such converters are known as
buck-boost converters. Standard V- and I- converters restrict output to either
lower or higher, known as buck or boost converters.
- Greater
Efficiency: Impedance Source (Z-Source) converters reduce common-mode
voltage leading to greater converter efficiency.
