Abstract :
Furthermore, an H-bridge class-S modulator will be implemented in order to depict the impact of the different PWM waveform rates in its efficiency. It will be shown that in PWM modulators most important than PAPR is the PMPR figure of merit, since the required modulation bandwidth changes with this relationship considerably. Moreover a closed analysis will be done for well known modulated waveforms. Furthermore, an H-bridge class-S modulator will be implemented in order to depict the impact of the different PWM waveform rates in its efficiency.
