“…However, these chokes increase the weight of the converter and introduce additional losses. Impedance balancing of power and neutral line can provide satisfactory noise cancellation results without application of any additional chokes [10]. However, it is critical to develop an equivalent noise model of the converter for impedance balancing.…”

“…However, large dv/dt and di/dt in GaN-FET based converters act as primary sources for conducted and radiated electromagnetic interference (EMI) [10], [11] . In such converters, parasitic capacitances in the circuit layout become critical at fast switching transitions (typically 5-20 ns) [12].…”

“…A recent publication [12] discusses the conducted emissions of WBG based motor drives. Various publications [10], [13], [15], [16] discuss conducted noise models for different DC-DC converter topologies. The fact that these publications address different topologies signifies the importance of identifying noise sources in novel topologies as well.…”

High Step-up converters have numerous applications in renewable energy systems and electric automotive industry. To improve the power density, an interleaved high step-up boost converter with coupled inductor was proposed. However, for practical applications it is compulsory that this topology must comply with the CISPR standards. Therefore, to identify the noise sources in the analyzed converter, an equivalent noise modelling is conducted. These models revealed the dependency of inductor windings on different noise sources. For experimental analysis of the conducted emissions of this topology, GaN FETs based prototype is designed. Several tests were carried out to find the effect of various factors on noise emission. As results of tests, 1) Increasing the switching frequency generates increase in the noise spikes 2) Noise emissions from the converter do depend on its mode of operation 3) High peaks of noise are generated at low frequency range by reducing the voltage transition time across the switch.

“…The traditional boost converters are preferred for their simple structure and low cost; however, they usually produce high input current ripples. For high voltage gain, this converter needs to work at a high duty ratio cycle, which causes switching problems [9][10][11][12][13].…”

A New Efficient Step-Up Boost Converter with CLD Cell for Electric Vehicle and New Energy Systems

et al. 2020

An increase in demand for renewable energy resources, energy storage technologies, and electric vehicles requires high-power level DC-DC converters. The DC-DC converter that is suitable for high-power conversion applications (i.e., resonant, full-bridge or the dual-active bridge) requires magnetic transformer coupling between input and output stage. However, transformer design in these converters remains a challenging problem, with several non-linear scaling issues that need to be simultaneously optimized to reduce losses and maintain acceptable performance. In this paper, a new transformer-less high step-up boost converter with a charge pump capacitorand capacitor-inductor-diode CLD cell is proposed using dynamic modeling. The experimental and simulation results of the proposed converter are carried out in a laboratory and through Matlab Simulink, where 10 V is given as an input voltage, and at the output, 100 V achieved in the proposed converter. A comparative analysis of the proposed converter has also been done with a conventional quadratic converter that has similar parameters. The results suggest that the proposed converter can obtain high voltage gain without operating at the maximum duty cycle and is more efficient than the conventional converter.

“…The fast switching operation of power device is necessary for higher frequency operation of the circuit. High di=dt and dv=dt in the transient response of power device induces significantly large and wide band noise spectrum [1,2]. Differential mode noise, which is accompanied with switching operation of power device, is unavoidable in the normal operation of power conversion circuit It can be sufficiently suppressed by filter in the circuit.…”

This paper proposes an evaluation method for common mode (CM) and differential mode (DM) of conducted emission in the power line measured with a Vector signal analyzer (VSA). The termination disturbance voltage of the two LISN (line impedance stabilization network) are synchronously measured with a 2ch VSA. The results of vector signal processing in the proposed method in experimentally validation by comparing with the results of conventional method for noise mode separation by using CMDM switch.
