Patent number: 9994109Abstract: A boost converter is configured of a boost chopper having a diode of an upper arm and a switching element of a lower arm. Output power from a battery to a load is limited such that a current flowing through boost converter does not exceed a current upper limit value for thermal protection of boost converter. The current upper limit value is set based not only on a cooling water temperature of boost converter but also on an output voltage VH of boost converter, in consideration of characteristics that, as output voltage VH rises, an amount of heat generated in diode decreases, diode being regarded as a main target of thermal protection since it receives a power running current to load. Thereby, the boost converter can be protected from overheating without excessively deteriorating vehicle traveling performance.Type: GrantFiled: December 1, 2015Date of Patent: June 12, 2018Assignee: Toyota Jidosha Kabushiki KaishaInventors: Etsushi Taguchi, Akihiro Takahashi
