Abstract :
Carrier signals for pulsewidth modulation are generated using simple filters operating on the waveforms readily available in a power converter. Also containing the averaged dynamics, such carrier signals can be bonded to a signal to be controlled to realise fast, linear transient responses. The operating principle and circuitry are described and validated for the buck and boost DC-DC converters
