A 4 MHz monolithic digital single-inductor dual-output (DSIDO) buck/boost converter based on 10-bit ΣΔ modulator and 4-bit delay line digital pulse width modulator (DPWM) is presented. Window delay line ADCs, digital PID compensator and DPWM with 2nd ΣΔ modulator are utilized in the converter to pursue highly flexible and intelligent power management. Digital Extend PWM control method is proposed...
To verify the hardware and software performance of a common rail turbocharged diesel engine ECU, a simulator was built up based on dSPACE hardware boards. The interface between the simulator and the ECU was developed. The real-time simulation model of the common rail turbocharged diesel engine was setup up in enDyna and successfully downloaded to the simulator. The monitor interface was designed in...
For that automotive engine fueled with natural gas required more spark energy in starting process, a new type of ignition system was developed to solve the questions that engine was hard to start and was misfired in heavy load. ATmaga8 single-chip microcontroller was adopted as the core of the ignition control system and C language was used to develop engine program. Based on the cylinder detection...
