“…The era of metal oxide silicon field effect transistor (MOSFET) is fading and being replenished by IGBT in most of the advanced and latest applications. In the average current control analysed for high voltage gain with the use of coupled inductor and voltage multiplier circuit along with IBC with hardware of 170 W at switching of 100 kHz has yielded efficiency of 95.1% as discussed by Diaz-Saldierna et al (2012) and Freitas et al (2015). Dynamic modelling and control of IBC with extremely high duty cycles capturing the reverse recovery, electromagnetic interference (EMI) effects and system behaviours with loads are elaborated with commutation process during zero voltage switching and zero current switching by Mahmoud et al (2017) and Wen et al (2006).…”

The proposed study is improvised value-engineered modifications for the basic interleaved boost converter (IBC) by including relevant modifications in circuits, which is expected for a better performance in switching with reduction in losses. The newly modified IBC circuit with insulated gate bipolar transistor (IGBT) along with converter has been experimented by simulations and the results are tabulated to modified IBC with metal oxide silicon field effect transistors. Further experimental analysis and validations of the proposed simulation with hardware developed adopting model SKM195GB066D consisting of IGBTs is presented. This study further enhances and summarises the optimum utilisation and the performance of IBC with the proposed IGBT modules that synchronises power diode. Enhancing the simulation outcomes, the hardware is proposed and developed to be tested for a load up to 1.5 kW with the evaluation of key parameters such as efficiency of the converter.

It is known that most of the renewable energy resources are the DC type. However, DC microgrids do not have zero crossing in current and voltage. This results in serious concerns about the circuit breaking and fault current limiting in the power system. Conventional thyristor-based DC fault current limiters (FCLs) may provide possible solutions for this problem. Unfortunately, a permanent interruption would arise on the system in case of a temporary fault. For this reason, this proposal aims to develop an integration system of the circuit breaker and FCL using a feedback-controlled zero-voltage switching method. In this proposed model, a load current is detected and an appropriate switch signal is thus generated by the controller based on the feedback-control strategy. Once the load current is beyond the predefined value, the switch will be opened to reduce the current immediately for a period of time set by the timer in advance. Then, the switch will be closed again to raise the current continuously until the overload threshold is reached. The switching transition duration is located at the resonant zero voltage, so that no switching power is required. Both simulation and practical performance results confirm that an expected constant load current can be well controlled over an expected range.

Traditional overload protection methods usually use either breakers or converters, focused on the side of power supply. However, these schemes may suffer from a slow response time or load dependence. Particularly, the facility may not be able to remain as a regular working condition when an overload occurs. To resolve this problem, the proposed feedbackcontrolling resonant switching algorithm aims to provide an expected load constant current to protect the load from overload without sacrifice for a normal load operation. On the basis of a negative feedback-control mechanism, the proposed model can detect the load current and thus generate an appropriate switch signal fast and accurately. The switch open period is decided by the model parameters and load current, and it can be set in advance by the timer. On the other hand, the switch closed period is determined by the expected load current that is independent on the load size. The switching acts at the resonant zero-voltage point, so that no power is consumed during the switching action. The performance simulation with DC 28 V supply confirms that the proposed model can maintain a predefined load constant current for an overload protection effectively.
