Simulation Tool을 이용한 위상제어 컨버터의 동작 특성 분석-Operation Characteristics Analysis of Phase Control Converter using Simulation Tool by SU -YEON LIM
ABSTRACT
Presently, the specific gravity of the used field of the AC-AC phase control converter in which the effective value and frequency have got the output of the other alternating current by approving the alternating current used for the motoring and dimming circuit, and etc. As the development of the dimming circuit, controlling the brightness of the illumination by the expansion of the illumination industry market using LED along with the development of the various product using the electric motor including an air-conditioner, refrigerator, washing machine, and etc. Due to the development of an industry as the driving source and etc. Increases. In using the power offset required in the device connected to the output terminal to the object using the phase control, it is due to be convenient.
The AC-AC phase control converter uses in order to set the power offset of the load in which the part of the input voltage waveform is not delivered to the load and while a switching occurs for every cycle of the alternating current, that is the input voltage, requiring the power offset which is lower than the input electrode value by lowering the effective value of the output voltage and output current and the power offset taking the load.
In this paper, PSIM program and PSpice program were used. PSIM program is the program which it simulates by using the ideal element. PSpice program is the program which selects and can simulate the actually used device
By using the single phase control converter and three phase control converter (Y-Y wiring) and three phase control converter (Y-∆ wiring) PSIM program and PSpice program among the AC-AC phase control converter among the simulation program, this paper enforced a simulation and inquired into the difference of two programs.

Abstract: A zero-voltage and zero-current switching full bridge converter with series resonance tank is presented in this study.
This converter is based on standard full bridge topology and a series capacitor is added in the primary side to reset the leakage
inductance current without any additional auxiliary circuit. Leakage inductance of the transformer is used as the resonance
inductance. Using series resonance tank and applying control pulses with fix frequency, zero-voltage switching for leading
leg and zero-current switching for lagging leg is achieved. The output power is controlled using phase shift technique. In the
proposed converter, soft-switching condition is attained for wide range of load variation. Due to its high performance and
minimum additional components with respect to regular converter, this converter can be applied for medium to high-power
applications. Topology and operating modes are discussed and the validity of theoretical analysis is verified by prototype
experimental results.

ABSTRACT
With the rapid development of the world’s aerospace technologies, a high-power
and high-reliability space high-voltage power supply is significantly required by new
generation of applications, including high-power electric propulsion, space welding,
deep space exploration, and space solar power stations. However, it is quite difficult
for space power supplies to directly achieve high-voltage output from the bus, because
of the harshness of the space environment and the performance limitations of existing
aerospace-grade electronic components. This paper proposes a high-voltage power
supply module design for space welding applications, which outputs 1 kV and
200 W when the input is 100 V. This paper also improves the efficiency of the high-
voltage converter with a phase-shifted full-bridge series resonant circuit, then simulates
the optimized power module and the electric field distribution of the high-voltage
circuit board.

Powerful Knowledge 9 - Magnetics Design for High Performance Power Converters
Magnetics design is often the most overlooked aspect of the design of power electronic converters. This is episode 9 of our 'Powerful Knowledge' series and we go into some depths of how to approach magnetics design using energy storage as a starting point with an example of a mains input 50W flyback converter running at 100kHz switching frequency.
We cover aspects such as winding structure, basic core loss modelling, impacting of fringing fields near the airgap and practical characterization.
