무전극 램프(EFC)의 전등은 램프 양단에 고주파를 갖는 고전압을 인가해야 한다. 종래의 무전극 램프의 구동 회로로 선형 증폭기가 이용되어져 왔으나, 낮은 에너지 변환 효율로 인해 PWM 스위칭 방식의 인버터로 교체되고 있다. 그러나 고주파 스위칭시 인버터의 스위칭 소자에서 스위칭 손실의 증가 및 노이즈 발생의 문제로 인해 PWM 인버터는 고주파 동작이 제한된다. 이러한 문제점을 해결하기 위해 영전압 스위칭 기술을 PWM 인버터에 적용하여 고주파 스위칭이 가능하고, 또한 스위칭 손실과 노이즈 발생을 줄일 수 있다. 본 논문에서는, 무전극 램프 구동용 인버터의 역률 개선 회로로서 이용될 수 있는 승압형 컨버터에 있어서 소형화 및 고전력 밀도에 큰 장점을 갖는 영전압 천이 PWM 승압형 컨버터에 관한여 서술하였다. 영전압 천이 PWM 승압형 컨버터의 정상상태 동작을 구간별로 해석하였으며, 이를 통하여 영전압 스위칭 조건을 도출하였다. 또한 이 컨버터를 무전극 램프 구동용 인버터의 역률 개선 회로에 적용, 실험을 하였으며 그 결과 0.99이상의 역률을 달성함을써 역률 개선 동작의 타당성을 입증하였다. Driving the electrodeless fluorescent lamp, the high AC voltage with high frequency is required. The linear power amplifier has been widely used as a driving circuit of electrode-less fluorescent lamp(EFL). However, the low efficiency of the power amplifier causes the driving circuit to be replaced by a PWM switching inverter. In other to use a PWM switching inverter as the driving circuit of an electrode-less fluorescent lamp, the high switching frequency is required But due to the switching loss at switches of the inverter, the limitation of high switching frequency appears in the inverter. One solution to this limitation is to reduce the switching loss by using the zero voltage switching technique. In this paper, an application of the ZVT-PWM(Zero-Voltage-Transition) boost converter, which has great advantage on mini-on and high power density, to the power factor correction circuit of the EFL(Eiectrode1ess Fluorescent Lamp) inverter i s studied. The operation principle of the converter are described to identify the power factor correction characteristics of the inverter. Experimentally obtaining the high power factor above 0.99, it is verified that the power factor correction of the EFL inverter successfully achieved.

The development of advanced Insulated Gate Bipolar Transistor(IGBT)has enabled high-frequency switching operation and has improved the performance of PWh4 inverters for motor drive. However, the high rate of dv/dt of IGBT has adverse effects on motor insulation stress. In many motor drive applications, the inverter and motor are separated and it requires long motor type. The long cable contributes high frequency ringing at the motor terminal and it results in hight surge voltage which stresses the motor insulation. The inverter output filter and RDC snubber are conventional method which can reduce the surge voltage. In this paper, we propose the new low loss snubber to reduce the motor terminal surge voltage. The snubber consists of the series connection of charging/discharging capacitor and the voltage-clamped capacitor. At IGBT turn-off, the snubber starts to operate when the IGBT voltage reaches the voltage-clamped level. Since dv/dt is decreased by snubber operating, the peak level of the surge voltage can be reduced. Also the snubber operates at the IGBT voltage above the voltage-clamped level, the snubber loss is largely reduced comparing with RDC snubber. The proposed snubber enables to reduce the motor terminal surge voltage with low loss.

Background and Objectives: Maternal alcohol abuse is considered to be one of the most prominent cause of neurobiological malformations in the postnatal and adult life of the offspring. In this study, we investigated the effects of maternal alcohol drinking on the postnatal development of NPY-containing neuron, and, the influence of thyroxine treatment on the cerebral cortex and hippocampus of pups of alcohol abused mother. Materials and Method: Time-pregnant rats were divided into three groups. Alcohol-fed group A received 35 calories of liquid alcohol diet daily from gestation day 6; control pair-fed group B was fed a liquid diet in dextrin replaced alcohol isocalorically: alcohol + T4 group C received 35 calories liquid alcohol diet and exogenous thyroxine subcutaneously. Results: Group C showed prominent NPY immunoreactivity in the cerebral cortex compared to group A and B at P7. In group C, NPY-containing neurons were widely distributed in the all layers of cerebral cortex after P14. Besides, numerical decrease of NPY-containing neuron as age increases was not found in group C. However, the decrease of NPY-containing neuron was clearly observed in group A compared to group C after P14. In hippocampus, group Band C were appeared similar patterns after P7. Additionally, in group C, NPY immunoreactivity was prominently appeared in CA2 and CA3 at P14 as compared to group B. Conclusions: The present results showed the increase of intensity and number of NPY-containing neurons in cerebral cortex and hippocampus of pups of exogenous T₄ supplemented alcohol-exposed dams as compared to control pair-fed and alcohol-exposed pups at P7. It presumably suggest that NPY-containing neurons might be regulated by the early postnatal growth stimulatory effect of the exogenously supplemented T₄. Therefore, the increase of NPY synthesis caused by maternal administration of exogenous thyroxine may ameliorate fetal alcohol effect, one of the ill effects as a result of the dysthyroid state following maternal alcohol abuse.
