Interleaved DC-DC Converter with Discrete Duty Cycle and Open Loop Control

Interleaved DC-DC Converter with Discrete Duty Cycle and Open Loop Control

The authors present the control principle of the multiphase interleaved DC-DC converter that can be used to vastly reduce output current ripple of the converter. The control algorithm can be easily implemented by using microcontroller without current loop in each phase. The converter works in discon...
