摘要： A device and a method for controlling a high side DC/DC converter (HDC) of a hybrid vehicle are provided. The switching frequency of the HDC is variably adjusted based on situations of temperatures of an inductor and an IGBT switching element, which constitute the HDC, to maintain a balance between the temperatures of the inductor and the IGBT switching element. Accordingly, temperatures of the inductor and the IGBT switching element are detected, and the switching frequency of the HDC is variably adjusted based on a situation for each temperature of each element to maintain a balance between the temperatures of the inductor and the IGBT switching element, thereby improving the utilization rate of the IGBT switching element.

摘要： A current sensing apparatus includes: a temperature sensor configured to sense a temperature of a power converter; a current sensing unit configured to sense an input current of the power converter; and a central processing unit (CPU) configured to control an operation of the power converter in response to the sensed temperature of the power converter and the sensed input current of the power converter. The CPU includes a compensation unit configured to store, upon receiving an indication of the sensed temperature of the power converter from the temperature sensor, an operation voltage of at least one diode included in the current sensing unit in a map, and to compensate for an error of a sensing current based on the stored operation voltage when the current sensing unit senses the input current.

摘要： A power conversion system for vehicles is provided. The system includes a first energy storage device and a charging device with a rectification circuit for rectifying AC power to generate a DC link voltage. A DC-DC converter converts the level of the DC link voltage to generate a charging voltage of the first energy storage device. A low voltage DC-DC converter selectively down-converts one of the voltage of the first energy storage device and the DC link voltage to output a low voltage having a predetermined level. The low voltage DC-DC converter selectively converts one of the voltage of the first energy storage device and the DC link voltage into the low voltage based on whether the first energy storage device is charged according to input of the AC power.
