This paper introduces a novel tunable inductor whose inductance can be adjusted continuously in a large range. The new inductor has one winding wrapped on a magnetic flux valve (MFV) and two C-cores attached to each side of the MFV to form a closed magnetic circuit. Its inductance can be altered continuously by applying an external control voltage on the MFV. This paper presents the concept, configuration,...
This paper proposes a new scalable and reconfigurable battery pack (SRBP), which consists of reconfigurable battery modules (RBMs) and a buffer inductor. Two SRBPs are then connected in series to form a single phase of a multiphase scalable and reconfigurable battery system (SRBS). The SRBS has a flexible interface with external systems with an adjustable DC or a multilevel AC voltage output and is...
This paper proposes an adaptive interconnection and damping assignment (IDA) passivity-based controller (PBC) with a complementary proportional integral (PI) controller for dc–dc boost converters with constant power loads (CPLs). The plant is modeled as a port-controlled Hamiltonian system (PCHS). A virtual circuit that interprets the parameters of the PCHS is then derived to determine the parameters...
Isolated converters are desirable in the DC-DC power conversion applications where isolation or a large voltage step-up gain is needed. Traditional isolated DC-DC converters either utilize many switches to achieve high efficiency or use few switches which result in low efficiency. This paper proposes a new single-switch isolated DC-DC converter for maximum power point tracking (MPPT) control and voltage...
