An improved automotive power distribution system using nonlinear resonant switch converters - Power Electronics, IEEE Transactions on

چکیده
Insertion of a dc-dc converter between the automobile battery and electrical loads is proposed. This would allow gradual conversion to higher battery voltage, regulation of dc distribution voltage, and multiple distribution voltage levels. Switching loss arising from parasitic inductances is a serious problem in this application. The nonlinear resonant switch can remove this source of loss, achieving zero current switching without sacrificing conduction loss or MOSFET switch utilization. A low-voltage high-current nonlinear resonant switch converter operating at 700 kHz and producing 600 W is described.

A nonlinear model for zero-current-switch quasi-resonant-converters is proposed which can be derived easily using simple analytical techniques. It is readily accepted by MATLAB for analysis and simulation in fast speed. Simulations have shown its accuracy even for large-signal transient dynamics. The condition for zero-current switching is also identified from this model.

متن کاملNonlinear-Carrier Control for High-Power-Factor Boost Rectifiers - Power Electronics, IEEE Transactions on
Novel nonlinear-carrier (NLC) controllers are proposed for high-power-factor boost rectifiers. In the NLC controllers, the switch duty ratio is determined by comparing a signal derived from the main switch current with a periodic, nonlinear carrier waveform. As a result, the average input current follows the input line voltage. The technique is suitable for boost converters operating in the con...

In this paper, nonlinear-carrier (NLC) control is proposed for high-power-factor rectifiers based on flyback, Ćuk, Sepic, and other up–down converters operated in the continuous conduction mode (CCM). In the NLC controller, the switch duty ratio is determined by comparing a signal proportional to the integral of the switch current with a periodic nonlinearcarrier waveform. The shape of the NLC ...
