Pulse-frequency modulation (PFM) is a modulation method for representing an analog signal using only two levels (1 and 0). It is analogous to pulse-width modulation (PWM), in which the magnitude of an analog signal is encoded in the duty cycle of a square wave. Unlike PWM, in which the width of square … See more PFM is a method of encoding analog signals into trains of square pulses and therefore has a wide variety of applications. There are practical difficulties in the design of electronics when working with non-fixed … See more • Determining Buck Converter Efficiency in PFM Mode • Pulse Frequency Modulation in Google Patents See more PFM mode is a common technique for increasing the efficiency of switching step-down DC-DC converters (buck converters) when driving light … See more • Pulse-amplitude modulation • Pulse-code modulation • Pulse-density modulation See more WebA novel control strategy combined pulse frequency modulation (PFM) with unilateral dual-phase-shift (DPS) control is proposed in this work. By controlling the switches in the converter, the forward buck mode operation can be realised under PFM control, as well as the backward boost mode WebPulse frequency modulation mode in buck converter MAX15062.
