Combined Energies

Novel Power Electronics for Distributed Generation and Energy Storage Applications

Hydrogen+Batteries+Fuel Cell Exhibit Hannover Messe 2018 Efficient by design.

Company Overview

• Combined Energies is a product development and manufacturing startup

located in upstate New York, USA, focused on providing power electronics for the clean technology market.

• Formed in 2011, the founders were pursuing residential CHP fuel cells.

Lacking investment interest, the company pivoted to pursue the development of a DC-DC power converter technology specifically for fuel

• cells. Recently we’ve expanded our interests to include renewables, energy

storage and fuel cell range extenders.

• Combined Energies was granted at US Patent 9,413,271 for our high boost,

bi-directional converter and was recently granted U.S. Patent 9,906,039 which claims our high boost converter with multiple DC inputs. An EU patent has been filed.

Our Product: The Marathon LR

Motivation: There is a need for power electronics that efficiently and cost effectively convert variable, low voltage DC power into steady, high voltage DC.

0.75 0.70 0.65 0.60 0.55 Cell Voltage Life Minimum voltage for inverter operation Area of increased energy recovery Life increase

Typical voltage degradation curve End of life with current DC to DC converters Increased voltage range with Marathon LR

Variable Low Voltage Input High Efficiency > 10:1 Boost Bi-Directional

Industries that Benefit

The Marathon LR- Efficient by design.

Solution: Combines Gallium Nitride (GaN) FETs, high current, DC boost topology with a transformer stage to create a single power conversion device that provides:

• Greater than 10:1 boost

ratio

• High efficiency (>95%) at

very low voltages

• No active cooling

requirements

• Bi-directional or uni-

directional operation

• Grid isolation

10kW building blocks- 3.3kW X 3
