The principle of operation of the AICS is based on a proposed input current shaping method (the series connection of a voltage source and a loss-free resistor between the input rectifier and the bulk capacitor). Moreover, the HBCC converter presents excellent features for low output voltage conversion due to the fact that it is possible to use self-driven synchronous rectification on it. In this paper, both the HBCC and the AICS are combined to obtain a single stage AC-to-DC converter that complies with IEC 1000-3-2 regulations with a high efficiency and at a very low cost.","PeriodicalId":287192,"journal":{"name":"APEC '99.

The characteristics of the proposed lighting system are high performance, high power factor with low input current harmonic distortion, dimming capability, low current lamps crest factor, and lower cost when compared with the traditional system with similar characteristics. The use of this system in place of the conventional electromagnetic ballast results in lower power consumption and reduced maintenance cost, because the electronic system has higher efficiency and longer lamp lifetime than the electromagnetic ballast. In comparison with the conventional electronic ballast, the proposed system presents a significant reduction of cost. This reduction becomes more meaningful with the growing of the lamp number. The description of the lighting system, design procedure and experimental results taken from a 1.2 kW prototype are included in the paper. The proposed lighting system is composed of a high power-factor rectifier that supplies a high-frequency zero-voltage-switching (ZVS) inverter. The output voltage of the AC-DC converter is regulated, maintaining the power of the lamps constant, even for large variations in the utility voltage.","PeriodicalId":287192,"journal":{"name":"APEC '99.

A six-switch PWM converter is utilized to convert a three-phase power from a WTG to a single-phase electric utility. The proposed converter consists of two stages. The first stage is a variable frequency PWM converter with 4-IGBTs to control the output power of the generator. The second stage employs 2-IGBTs to return the power to the electric utility. These two stages have common DC-link. The utility output current is sinusoidal with a good quality. Suitable PWM control via space vector modulation is designed to control the generator. Current regulated PWM is used to control the utility side. Results from the simulation of the power converter are presented in this paper. The proposed converter is suitable for utility interface of WTGs up to 20 kW ratings.","PeriodicalId":287192,"journal":{"name":"APEC '99.

Since the circuit performs soft-switching by resonating a capacitor and a motor winding, the voltage across the winding can be higher than twice the DC source voltage. Hence the circuit produces less EMI due to the application of soft-switching, and the output torque is increased by means of higher voltage. Moreover, because the proposed circuit utilizes only one series switching device between the DC source and the winding, system efficiency is also increased.","PeriodicalId":287192,"journal":{"name":"APEC '99.
