Patent number: 11458802Abstract: An optimized power converter for use in a transport electrical system that provides power to a transport climate control system is provided. The optimized power converter includes an optimized DC/DC converter and an inverter/active rectifier. The optimized DC/DC converter is only boosts a voltage level when current is directed from a rechargeable energy storage to the inverter/active rectifier and only bucks a voltage level when current is directed from the inverter/active rectifier to the rechargeable energy storage. In a charging mode, the inverter/active rectifier converts three phase AC power into DC power, and the optimized power converter bucks the DC power to a voltage level that is acceptable for charging the rechargeable energy storage. In a discharge mode, the optimized DC/DC converter boosts voltage from the rechargeable energy storage, and the inverter/active rectifier converts boosted DC power into three phase AC power for powering a transport climate control system load.Type: GrantFiled: September 9, 2019Date of Patent: October 4, 2022Assignee: Thermo King CorporationInventors: Marcelo Andrade Dias, Ryan Wayne Schumacher, Mark D.
