Comparison of single- and double-sided pulse width modulated signals with non-linear predistortion [PDF]
, 2012 Class D amplifiers are based on a low-bit pulse width modulated (PWM) signal reconstructed through the lowpass characteristic of the loudspeaker. To create a PWM signal, a non-linear conversion from a standard pulse code modulated (PCM) signal has to be ...

IET Electric Power Applications, Volume 16, Issue 2, Page 190-205, February 2022., 2022 Abstract Thermal stress is one of the most important factors leading to power module failure. Under the load condition of high current with low fundamental frequency or largely changed load current, it would cause high junction temperature swing amplitude (JTSA) of chips, which could accelerate the failure of power module.
