PWM Signal Measurement Issues

2022 IEEE International Workshop on Metrology for Automotive (MetroAutomotive), 2022
The real-time control of the operation of an electric vehicle made by the on-board control units requires measurements on different types of power signals from the DC power supply of the batteries to the PWM signals with which the inverter powers the engine.

Analysis of PWM Frequency Control to Improve the Lifetime of PWM Inverter

IEEE Transactions on Industry Applications, 2009
Studies have shown that the power cycling Mean Time to Failure (MTTF) of the IGBT bond wire in an adjustable speed drive (ASD) may be very short under some very common conditions. This paper proposes a switching frequency reduction method based on junction temperature variation (ΔTj) of the inverter IGBT. It has the following advantages.

Sectionalized PWM (S-PWM): A new multilevel modulation strategy

2008 IEEE International Symposium on Circuits and Systems, 2008
The paper presents a novel multilevel PWM strategy that employs a split section reference waveform with phase-shifted carriers to produce harmonically superior PWM signals. The multilevel PWM switching patterns provide a higher dynamic range than what has been reported in the literature.

FPGA implementation of PWM pattern generators [for PWM invertors]

Canadian Conference on Electrical and Computer Engineering 2001. Conference Proceedings (Cat. No.01TH8555), 2002
Pulse width modulation is used in power converters to modulate a reference signal into gating pulses for IGBT switches. This conversion can be carried out using analog circuits or digital circuits, such as DSPs and microcontrollers. A more efficient and faster solution is the use of field programmable gate arrays (FPGA).
