A modeling approach for the electrochemical batteries, which is suitable for in-circuit parameter extraction is presented. The charge flow in an electrode reaction is governed by the mass transport regime within the cells. For sufficiently higher charge flow rates, the mass transport rate decides the limit. Hence modeling the battery, centered around the mass transport mechanism can have the benefits...
In this paper, a fourth-order non-isolated bidirectional converter is proposed for load power management in low-voltage DC grid. With state-space and discrete-time modeling technique, the proposed bidirectional converter is modeled, and small-signal transfer functions are obtained. A digital compensator is designed using these transfer functions both for the charger and discharging cases. The converter...
This paper proposes a new circuit topology of MMC for DC to AC applications. The main advantage of the proposed topology is the elimination of lower arms of conventional MMC. Additionally, the DC bus voltage magnitude is half compared to conventional MMC. This is achieved by replacing the lower arms of conventional MMC topology with LC filter. The LC filter is designed to be a second order band stop...
In this paper a simple and robust parameter estimation methodology for single phase transformer and three phase induction motor is proposed using particle swarm optimization (PSO) technique. Here the equivalent circuit parameters and losses of a single phase transformer and a three phase induction motor are obtained using PSO technique. The obtained results from PSO are verified by comparing it with...
Synchronous buck converters with normally off MOSFETs are widely used for point of load converters. Recently introduced, normally on, high electron mobility, power devices shown to have excellent switching characteristics with very low on state voltage drop. To drive a normally on MOSFET, a gate drive with bipolar voltage capability is required. Generation of a bipolar voltage from a positive voltage...
