This paper presents a global tracking passivity–based proportional–integral (PI) control for output voltage regulation of a dc–dc Buck converter. The proposed controller is based on passivity formulation since dc–dc Buck converter has a passive structure in open–loop. Additionally, the ...
I have a drv8301 and the buck converter components soldered to my board. I added a 3.9 Ohm resistive load at the 3.3V output. At 12 V I see 900mA current at the output and 3.214V. At both 24V and 48V the current at the output drops to 100mA and my output volta...
Total harmonic distortion (THD)buck converterbuck/boost converterpower factor (PF)Buck power factor correction (PFC) converter is widely used for a broad range of AC/DC applications because of its many advantages like protection against short circuit, high efficiency at ...
The LTC3443 Buck-Boost converter minimizes output voltage transient perturbations, and thus realizes the promise of Burst Mode operation to significantly increase battery run time. The LTC3443 incorporates an adaptive clamp on the VC pin—active during Burst Mode operation—which holds the error a...
Hi everybody, I've been running this model of a buck converter with simulink simscape. The inductor is in CCM, so the output voltage should be the input voltage times the duty cycle of the pulse. Somehow the output voltage is much higher. Somebody has an idea of what I'm doing ...
