In high power converter design, low-inductance busbar connecting DC capacitors and power devices is main concern to improve the quality of the whole power electronics system. This paper analyzes the impact of layer-number on the stray inductance of busbar taking a subway traction converter as example. The method of partial element equivalent circuit and the Q3D software were used to extract the stray inductance. The simulation and experimental results show that the stray inductance of three-layer busbar is lower than two-layer busbar with other same conditions.

Converter Design

Abstrak— Paper ini menampilkan desain double boost converter yang mempunyai kemampuan menggandakan tegangan dua kali lipat berturut  turut beban DC yang menghasilkan tegangan output tambahan atau cadangan suplai pada beban. Pada umumnya double boost converter ini adalah konverter daya DC to Dc meningkatkan tegangan dari input (pasokan) ke output (beban) di desain menunjukkan bahwa dengan inputan sumber AC yang di searahkan terlebih dulu dengan converter penyearah berfungsi untuk mengatur kecepatan motor BLDC. Untuk pengontrolan pada beban motor menggunakan PI controller ( Proportional Integrator) dimana  parameter PI controller diperoleh dari trial eror. PI controller juga berfungsi memperbaiki gelombang keluaran dan kecepatan motor BLDC. Kata kunci : Motor BLDC, Double Boost Converter, PI controller. Abstract— This paper features a double boost converter design that has the ability to double the successive voltage in a DC load which results in an additional output voltage or supply reserve at load. In general, this double boost converter is a DC to Dc power converter increasing the voltage from input (supply) to output (load) in the design shows that the input AC source is aligned first with the rectifier converter to regulate the speed of the BLDC motor. To control the motor load using a PI controller (Proportional Integrator) where the PI controller parameter is obtained from the trial error. The PI controller also functions to improve the wave output and speed of the BLDC motor.

In relation to power converter design, power density is increasing while the form factor isdecreasing. This trend generally reduces the rate of the cooling process, which increases the mutualthermal coupling among the surrounding power components. Most of the traditional modelsusually ignore the mutual effects or just focus on the conduction coupling. To deal with these factors,the thermal modeling for a boost converter system has been built to compare the junctiontemperatures (Tj) and the increments under different working conditions in order to consider theconduction coupling. A multi-variable thermal resistances model is proposed in this paper toincorporate the convection thermal coupling into the mutual thermal effects. The couplingresistances, MOSFET to the diode[...]
