International audienceThis paper focuses on the modeling of a power PiN diode. The focal point basis is the dependence on temperature. The PiN diode remains a difficult device to model mainly during switching transients. An advanced PiN diode temperature-dependent model is developed and implemented in VHDL-AMS. Heterogeneous simulation scheme including the circuit wiring parasitic components, the probe effects and the dependent diode models is successfully simulated using SIMPLORER simulator. Experimental data of several commercial PiN diodes are compared to simulation results at different temperature levels. A good rate of consistency is found

In this study, a novel control scheme for controlling a self-oscillating half-bridge series resonant converter for DC source and secondary battery interface is proposed. This new control scheme is used to control and regulate the DC output current of the converter. The proposed control scheme has the advantages of not only wide power regulation range, but also ease of output current control. In addition, it can achieve a stable and efficient zero-voltage-switching (ZVS) in a whole load range. The control principles of the proposed method are described in detail and its validity is verified through simulated and experimental results based on a 24 V 125 Ah battery charger. The maximum charging efficiency of the proposed topology during the overall charging period exceeds 90%.
