Development of Robust Discrete controller for Double Frequency Buck converter

A discrete controller is designed for high efficiency double frequency buck converter. This double frequency buck converter is comprised of two buck cells: one works at high frequency, and another works at low frequency. It operates in a way that current in the high frequency switch is diverted through the low frequency switch. Thus, the converter can operate at very high frequency without addi...

Design of Integrated Double Buck Boost Converter for Industrial Applications

An Integrated double buck boost converter is analyzed and the design methodology is made as a high power factor of the power supply for the power LED lamps. The IDBB converter features just one controlled switch and two inductors and is able to supply a solid-state lamp from the mains, providing high power factor. Here with a careful design of the converter, the filter capacitances can be made ...

A Double Closed-Loop Control Method for Quasi-Resonant Converter

To achieve the soft-switching condition and stabilize the output voltage of quasi-resonant converters, the paper proposes a double closed-loop control method (DCCM). In the inner loop, soft-switching is guaranteed with the off-time of the switch determined by the zero-crossing signal of the switching voltage. In the outer loop, the output voltage is regulated to be constant against load variati...

Nine level Double Flying Capacitor Multicell Converter Based on Phase Shifting Technique

Multicell converter are a very interesting alternative for medium and high power drives. This paper presents a new configuration of double flying capacitor (DFCM) converter. The main advantages of the proposed converter in comparison with FCM and stacked multicell converter are doubling the rms and the number of output voltage levels, improving the output voltage frequency spectrum, and cancell...
