Abstract
The objective of this SAE paper is to discuss a power stage partitioning which will provide a cost effective and flexible Infineon Technologies solution to control future E-Valve applications.
To fulfil environmental demands, E-Valve applications will enable car manufacturers to:
- Dynamically reduce the number of working cylinders according to the drivers' torque requirements
- Have an efficient and variable control over the engine load in various conditions
- Dispense with throttles and exhaust recirculation valves
The paper will describe:
- 1The integration of the 4 MosFET and the future technology development required for the next system optimization.
- 2Gate driver integration (3 different scenarios):
- Analog Interfacing between the μcontroller and the MosFETs with an integrated protection functionality (Scenario A).
- Smart gate driver In addition to the blocks mentioned in Scenario A, a VHDL block aimed at reducing the number of events requested at the μcontroller for cylinder control (Scenario B).
- Quasi-autonomous gate driver Small digital signal processor, in addition to the blocks mentioned in Scenario A, to reduce almost to “0” the number of events requested at the μcontroller for cylinder control (Scenario C).
