Low-power switched-mode power supply converters are used in applications where size and efficiency are critical. The buck converter size can be reduced by elimination of the bulky filter capacitor. The filtering function of this capacitor can be replaced by an output current ripple compensation circuit. The compensating circuit is applied, based on inductor current measurement and linear amplif...
This work presents the analysis of radiated EMI problems associated with DC-DC buck converters and the solutions for minimize the reverse recovery of the Drain-Bulk diode of the synchronous switching MOSFET. The DC-DC buck converter topology is used in computers and telecom applications because of its high power efficiency and multiple DC levels. For reducing the reverse recovery and its relate...
This paper develops a PI-like interval type-2 (IT2) fuzzy maximum power point tracking (MPPT) control method for a class of wind power generation and battery charging systems with DC/DC buck converters. After the brief model descriptions of the wind power turbine, generator and DC/DC buck converter, the proposed MPPT controller is designed using IT2 fuzzy control logics and its asymptotical sta...
Passivity{based feedback controllers are derived for the indirect stabilization of the average output voltage in Pulse{Width{Modulation (PWM) controlled dc{to{dc power converters of the \boost", \buck{boost" and \buck" types. The controller design is carried out on the basis of well known average PWM models of such circuits. These models are shown to be Euler{Lagrange systems corresponding to a...
A new resonant switch is introduced which employs nonlinear tank elements. Zero current switching is obtained. yet the peak transistor voltage and current stresses can approach those of an equivalent ideal PWM converter. Reduced switching loss without a substantial increase in conductbn loss is therefore possible. An approximate analysis is outlined, and transistorpeak voltage and current stres...
