Patent number: 10644587Abstract: Chargers and methods are provided which increase the charging efficiency of the chargers by implementing voltage amplitude modulation (VAM) instead of voltage frequency modulation. The charging voltage amplitude is modulated using feedback from at least one energy storage device that is being charged by the charger, while maintaining a charging voltage frequency constant at a LLC resonance frequency of the charger. A buck/boost configuration may be used to reduce maximal voltage levels and further optimize the charger's design.Type: GrantFiled: August 27, 2019Date of Patent: May 5, 2020Assignee: Storedot Ltd.Inventors: Leonid Spindler, Yegal Darhovsky, Daniel Aronov

Patent number: 6583999Abstract: A high efficiency, low voltage, high current, half-bridge, series resonant, multiphase, DC-DC power supply includes a combination of a boost type pre-regulator and a “base-sub” half-bridge, series resonant converter unit. The base-sub converter unit includes two half-bridge converters, connected in parallel to the boost type pre-regulator, and having outputs that are combined to produce the required output power. The DC-DC power supply has inherently a Zero Voltage and a Zero Current switching mode feature. The output voltage is the sum of the input voltage and of an additional (“Delta”) voltage, whose amplitude varies in order to insure that the output voltage is fixed and stable. In operation, the boost type pre-regulator converts only the additional “Delta” voltage, leading to a significant increase in efficiency of the boost type pre-regulator, and of the entire power supply.Type: GrantFiled: January 25, 2002Date of Patent: June 24, 2003Assignee: Appletec Ltd.Inventors: Leonid Spindler, Valery Gabdoulin
