DCM Frequency Control Algorithm for Multi-Phase DC-DC Boost Converters for Input Current Ripple Reduction

In this paper, a discontinuous conduction mode (DCM) frequency control algorithm is proposed to reduce the input current ripple of a multi-phase interleaved boost converter. Unlike conventional variable duty and constant frequency control, the proposed algorithm controls the switching frequency to regulate the output voltage. By fixing the duty ratio at 1/N in the N-phase interleaved boost conv...

Simulation of Combined Boost Converter Behavior with Positive Output Voltage and Investigation of Voltage Ripple at Output

In this paper, the behavior of a hybrid back-boost converter with a positive output voltage is simulated. This converter consists of an amplifier voltage converter called KY converter and a modified synchronous converter (SR). The converter operates in continuous conduction mode (CCM) and has a non-shock output current, reducing the current stress in the output capacitor and reducing the output...

A New Topology of Bidirectional Buck-Boost dc/dc Converter with Capability of Soft Switching and input Current Ripple Cancellation

In this paper, a new bidirectional buck-boost dc-dc converter with capability of soft switching and zero input current ripple is proposed. The coupled inductor is used in the proposed converter to eliminate the input current ripple. In the proposed converter, zero voltage switching (ZVS) and zero current switching (ZCS) can be obtained for the main and auxiliary switches, respectively. In addit...

Low Power Boost Converter for Portable Applications

Nickel Cadmium batteries are popular because they have a relatively low cost and offer a mature technology. Nickel Metal Hydride batteries have improved volumetric efficiency and have less environmental concerns than Nickel Cadmium. Lithium-Ion batteries are emerging as a leader in the portable market due to their high energy density. Lithium-Ion batteries have the highest initial cost, however...
