Design considerations for building robust circuit protection in electrified and increasingly automated vehicles.
Designing circuits for electrified vehicles is extremely challenging. To ensure robust and safe designs that can withstand overloads, transients, and electrostatic discharge (ESD), designers need to ensure their circuits have the necessary components that will prevent damage. This article presents recommendations for both circuit protection and efficient control using the on-board charger as an example circuit.
Hybrid vehicles, as seen in the Fig. 1 schematic, represent the worst-case scenario for designers who must develop circuitry that can withstand transients from both the internal combustion engine and the highpower electric motors. In this environment, the on-board charger must contend with the AC power line and its potential for generating overloads and transients.

Search Tips: Search Operators:AND, OR, NOT; Wild Cards; Using Quotes
SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
