Switch duty cycle

Splet26. okt. 2016 · Basically yes, that duty cycle is correct, but only when the converter is running in the continuous mode. For the discontinuous mode we can fairly easily equate the input energy to the output power and come up with a value for the output voltage or the duty cycle, but it will be different than for the continuous mode.

Splet17. mar. 2024 · Duty cycle: A duty cycleis the fraction of one period when a system or signal is active. We typically express a duty cycle as a ratio or percentage. A period is the time it takes for a signal to conclude a full ON-OFF cycle. Frequency: The rate at which something repeats or occurs over a particular period. Splet16. apr. 2003 · When operating in continuous conduction mode, the PMOS (high-side) switch has a duty cycle proportional to the step-down ratio, D = Vout / Vin For a switching frequency fs, the on-time of the PMOS switch will be Ton = D * (1/ fs) Thus, the Ton is dependent on both the switching frequency and the step-down ratio.
