“…Static inverters have a 400 Hz output frequency [2][3][4][5]. Inverters with 400 Hz output frequency are also preferred for marine, rail transport and laboratory research for a long time [6]. Although voltage-source static inverters (VSI) are studied and designed for such applications [7,8] current-source inverters could not find a place in the literature [4].…”

This paper analyses a new half-bridge current–source inverter for avionic systems. In the circuit, two 28 V batteries are used as inputs. These voltage sources are connected to inductors which create a constant current source. Then only two high-frequency switches are used to waveshape the positive and negative half-cycles. The SCR-based half-bridge allows positive and negative current flow properly. The inverter output uses a CL filter to remove PWM components and to obtain 400 Hz sinewave output. Simulation and HIL experiment results are provided with feedback control to prove the concept of the proposed topology. The study shows that the new current–source topology provides promising results while complying with aviation standards.

“…Aircraft make use of static inverters operating at the output frequency of 400 Hz (Sener et al , 2017; Abarzadeh and Kojabadi, 2016; Yuan et al , 2015). The Navy vessels have also been using this frequency for a long time (Khaligh et al , 2018). Various studies have been carried out on voltage-source inverters (VSI) (Zhao et al , 2014; Jiangbiao et al , 2018) (Figure 1).…”

Purpose This paper aims to present an inverter with a current-source input for 400 Hz avionic systems to have a system which removes DC-link capacitors and presents a high efficiency. Design/methodology/approach A battery-powered DC link inductor generates a constant-current source. A single high-frequency switch is used to provide a sinusoidally modulated current before the inverter. The output of the switch is “unfolded” by a thyristor-based H-bridge inverter to generate an AC output current. The system uses a CL low-pass filter to obtain a 400 Hz pure sine wave by removing pulse width modulation components. Findings Simulations and Typhoon HIL real-time experiments were performed with closed-loop control to validate the proposed inverter concept while meeting the critical standards of MIL-STD-704F. Originality/value This current source inverter topology is suitable for avionic systems that require 400 Hz output frequency. The topology uses small DC-link inductor and eliminates bulky capacitor which determines the inverter lifetime.

“…According to some statistics, using resonant converter is growing immediately in power electronics. Resonance converter can be utilized in different cases, such as LED drivers, 5 HF inverters, 6 electronic ballasts, 7 battery chargers, 8,9 motor drive, 10 multilevel converters, 11,12 LCD TV power supply, 13 renewable energy, 14,15 and even for Maglev due to high performance of these converters. 16 In Wan and Yang, 17,18 a general grouping of this type of converter has been stated: series resonant converter (SRC), parallel resonant converter (PRC), and series-parallel resonant converter (SPRC).…”

Summary In this paper, a new design procedure for LLC converter has been introduced. In fact, this method is a computer‐based design algorithm based on a numerical technique. In the process of designing, the value of the resonant element is obtained by solving the LLC converter fundamental equation. This converter will be controlled by using state feedback, such as output voltage variable. As a matter of fact, in a control system, the change of output voltage (because of load variation) will affect the switching frequency, so the output voltage will be tuned. In the designing process, the fundamental equations of LLC converter are obtained, and the value of the resonant elements is calculated. Also, a comparison analysis is carried out between the proposed and typical methods. The simulation is done to investigate the validity of the proposed method. Moreover, a prototype is manufactured, and the experimental test is done to evaluate its applicability.
