USING BATTERY CHARGER AS A HEATER - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240291394 titled 'USING BATTERY CHARGER AS A HEATER
Simplified Explanation:
This patent application describes a battery charger with a unique configuration that includes both AC side stacked half bridges and DC side stacked half bridges coupled to a transformer. The charger can operate by selectively providing a current path through the primary winding of the transformer without using an AC source, or through the secondary winding without connecting a battery.
- The battery charger has an AC side stacked half bridge configuration connected to the primary winding of a transformer.
- It also has a DC side stacked half bridge configuration connected to the secondary winding of the transformer.
- The charger can operate by either providing a current path through the primary winding without using an AC source, or through the secondary winding without connecting a battery.
- In one case, the DC side stacked half bridges alternate between switching states to connect a battery to the secondary winding.
- In the other case, the AC side stacked half bridges alternate between switching states to connect the AC source to the primary winding.
Potential Applications: - Electric vehicle charging stations - Renewable energy systems - Industrial battery charging systems
Problems Solved: - Efficient battery charging - Optimal use of transformer windings - Flexibility in charging different types of batteries
Benefits: - Faster charging times - Energy efficiency - Versatility in charging different battery types
Commercial Applications: Title: Innovative Battery Charger Technology for Various Industries This technology can be used in electric vehicle charging stations, renewable energy systems, and industrial battery charging systems.

Original Abstract Submitted
operating a battery charger having an ac side stacked half bridge configuration coupled to a primary winding of a transformer and a dc side stacked half bridge configuration coupled to a secondary winding of the transformer to provide heating can include either operating the ac side stacked half bridges to provide a current path through the primary winding that does not include an ac source or operating the dc side stacked half bridges to provide a current path through the secondary winding that does not include a battery. in the former case, operation can include operating the dc side stacked half bridges to alternate between switching states that selectively couple a battery to the secondary winding of the transformer. in the latter case, operation can include operating the ac side stacked half bridges to alternate between switching states that selectively couple the ac source to the primary winding.
