A system for a direct-current (DC) to alternating current (AC) inverter includes: a memory configured to store instructions; a main microcontroller configured to execute the stored instructions to control the inverter during non-timing-critical operation; and a safety controller configured to control the inverter during timing-critical operation.

Configurable fault and control safety architecture for inverter system

An engine data acquisition and control system measures cylinder pressure at a high degree of resolution and then processes it for portions of the combustion cycle of interest for performing combustion calculations. The data are utilized to calculate combustion parameters, and the combustion parameters may be utilized to control the engine's fuel and/or spark timing/duration, and other variables affecting the combustion process. The system architecture provides for acquisition of very large amounts of data without unduly loading the CPU.

Cylinder-pressure-based electronic engine controller and method

A method/system for measuring cylinder pressures of an internal combustion engine includes a crank angle sensor utilized to generate pressure readings at known angular intervals. Additional time-based pressure measurements are taken in selected angular windows between a pair of the angle-based pressure readings. Because the angle-based pressure measurements and the time-based pressure measurements occur at known times, the pressure as a function of the crank angle for the time-based pressure measurements can be determined. The cylinder pressure measurements can be utilized to calculate combustion parameters used for closed-loop engine control of fuel supply or other engine inputs.

Method of cylinder pressure sensor data/angle capture for low and high resolution

A control system for an electric heater, e.g., an electric catalyst heater (ECH), includes a current sensor, a voltage sensor, a switching element, and a control circuit. The control circuit is coupled to the current sensor, the voltage sensor and a control terminal of the switching element and varies a control signal on the control terminal to maintain the temperature of the heating element within a predetermined temperature range.
