US Patent:

20130169039, Jul 4, 2013
Filed:

Sep 6, 2012
Appl. No.:

13/605541
Inventors:

Charles Zhu - Canton MI, US
Chao Yan - Shanghai, CN
Lingjie Meng - Shanghai, CN
Sheng Hui Pai - Taoyuan Hsien, TW
Assignee:

DELTA ELECTRONICS, INC. - Taoyuan Hsien
DELTA ELECTRONICS (SHANGHAI) CO., LTD - Shanghai
International Classification:

B60L 1/00
US Classification:

307 101
Abstract:

Disclosed is a high-voltage battery converter including a first-order DC-DC converter electrically connected to a high-voltage battery for boosting a high DC voltage outputted by the high-voltage battery to an intermediate voltage having a predetermined voltage level when the high DC voltage is dropped, and a second-order DC-DC converter electrically connected to the first-order DC-DC converter for converting the intermediate voltage into a low DC voltage for driving at least one load in an electric vehicle.

US Patent:

20100322284, Dec 23, 2010
Filed:

Apr 26, 2010
Appl. No.:

12/767038
Inventors:

Charles Lizhi Zhu - Canton MI, US
Ajay V. Patwardhan - Canton MI, US
Fred Flett - Indio CA, US
Matthew R. Obrigkeit - Northville MI, US
Assignee:

CONTINENTAL AUTOMOTIVE SYSTEMS US, INC. - Deer Park IL
International Classification:

G01K 7/01
US Classification:

374178, 374E07035
Abstract:

A method for determining power semiconductor operating temperatures uses a database of measured temperatures. Each temperature is associated with operating conditions and determined by laboratory testing in an environment indicative of operation of the power semiconductors actual operations.
