The proposed topologies include only one magnetic device (a tapped-inductor) in the power topology. They are specially suitable to implement low cost ballasts for low power fluorescent lamps supplied from a low DC input voltage. The design methodology is focused in obtaining regulated luminous flux in the lamp, by regulating the power delivered to the lamp against variations in the input voltage and lamp characteristic. The design criteria to select the most appropriate control method and guides to obtain the best operating point depending on the desired output characteristic are presented. Finally, the complete design process is described.","PeriodicalId":347959,"journal":{"name":"APEC 2000. Fifteenth Annual IEEE Applied Power Electronics Conference and Exposition (Cat.

The proposed soft-switching technique is suitable for not only minority but also majority carrier semiconductor devices. The auxiliary switch of the proposed ZVZCS commutation cell is in parallel with the main switch, and therefore, there is no current stress on the main switch and diode. The operation principles of the proposed ZVZCS commutation cell are theoretically analyzed using the PWM boost converter topology as an example. Theoretical analysis, simulation and experimental results verify the validity of the PWM boost converter topology with the proposed ZVZCS commutation cell.","PeriodicalId":347959,"journal":{"name":"APEC 2000.

The conventional three phase engine generators for emergency power back up consist of diesel engine, generator and controller and usually back up three-phase power only. In the proposed engine generator, a generator conditioner is included to compensate phase current unbalance, which allows backup of a single-phase line. In addition, an AVR (auto voltage regulator) controller and a governor controller and a generator conditioner controller are integrated with single DSP (digital signal processor) control board to reduce cost and increase reliability. The generator conditioner shapes the generator currents sinusoidally in phase with generator voltages for any kind of load. The generator can be synchronized with the distribution power line and released without any power interruption or voltage spike since the load current is gradually changed from the distribution line to the generator, or vice versa. A 100 kVA engine-generator system is equipped on a 3.5 ton truck and the integrated controller is realized with TMS320C32PCMA. Experimental results for single and three-phase power back up at several load conditions are presented to verify the performance of the proposed mobile generator system.","PeriodicalId":347959,"journal":{"name":"APEC 2000.

Based on the derived small signal model, the closed loop compensation to dynamically stabilize each output circuit is presented.

The knowledge of their behavior in order to design both devices and circuits that would allow less switching losses is essential. In this paper, a distinct and interesting phenomenon in the charge dynamics of BJTs and IGBTs under ZCS operation is reported. It is shown that the difference in charge dynamics results in contradicting switching sequence requirements between BJTs and IGBTs. It is shown, with the help of two-dimensional device-circuit simulations, that in IGBTs, a majority of excess carriers are flushed out during the no-current regime while in the case of the BJT, most of carriers are removed by recombination after the device is turned off. In order to use the semiconductor switch optimally, IGBT turn-off should be delayed as much as possible, while, in the case of a BJT, the switch needs to be turned off as soon as possible after the zero-current condition is established. A careful choice of switching sequence is shown to result in a reduction in switching power loss by a factor of 2 in the case of the BJT and a factor of 3 in the case of the IGBT.","PeriodicalId":347959,"journal":{"name":"APEC 2000.

The converter presented in this paper uses a phase shift control with a flying capacitor in the primary side to achieve ZVS for the outer switches. Additionally, the converter uses an auxiliary circuit to reset the primary current during the freewheeling stage to achieve ZCS for the inner switches.
