A PV Powered High Gain Input-Parallel Output-Series DC/DC Converter with Dual Coupled Inductors

Meenu Jose Thekkan | Rosemin Parackal

Abstract: High voltage gain dc-dc converters are required in many industrial applications. Here a novel input-parallel output-series boost converter with dual coupled inductors and a voltage multiplier module for solar source is going to be designed. The primary windings of two coupled inductors are connected in parallel to share the input current and reduce the current ripple at the input. The secondary sides of two coupled inductors are connected in series to a regenerative capacitor by a diode for extending the voltage gain and balancing the primary currents. In addition, the active switches are turned on at zero current and the reverse recovery problem of diodes is alleviated by reasonable leakage inductances of the coupled inductors. Besides the converter has low voltage stress across the switches and energy of leakage inductances of the coupled inductors can be recycled.
