“…Omitting two unusual commutation strategies called basic current commutation breaks the principles of switching laws, especially soft switching techniques [13]. There are two major strategies for bidirectional switch commutation 1) current-direction-based strategies [14]- [16] and 2) voltage-direction-based strategies [10] and [17]. The other commutation strategies are based on both current-direction and voltage-magnitude.…”

The Commutation strategy of matrix converters for high-frequency unity power factor applications has been a challenge for years. The strategy should be simple, have a short duration, and possibly avoid current sensing. This paper proposes a new strategy for the bidirectional switch commutation of the three-phase to two-phase matrix converters supplying inductive power transfer (IPT) systems. This strategy's main merits are simplicity, the reduction of commutation time, and no need for detecting the load current sign, which is crucial for synthesizing the output voltage accurately. Pulse density modulation is used because of the high frequency output voltage and possibility of utilizing three phases in any particular output cycle leading sinusoidal shape of grid current. Presented simulation and experimental results verify the converter's appropriate function using the proposed strategy and a reduced switching state machine.

“…The control of the shoot-through state requires speed-up computations which can be achieved with a FPGA (Field-Programmable Gate Array) [13]. This paper proposes the use of the FPGA contained in MicroLabBox to implement the qZSC control [14], [15]. If necessary, the clock time and the sample time in the FPGA platform could be diminished until 10 ns (such high speed is unnecessary in our application).…”

Nowadays, power systems require new solutions to integrate renewable energies. In this paper, microgrids linked to MVDC are proposed through quasi-impedance-source converters to improve system reliability. Several prototypes are implemented using real-time platforms to analyze the system behavior, but the real-time implementation of the shoot-through state of the qZSC requires a very low time-step and sample time, which is not easy to achieve. The results obtained with these prototypes are included. Finally, a satisfactory solution is presented, implementing the power system in Typhoon HIL-402, the qZSC control in dSPACE MicroLabBox, and generating the gate signals in the FPGA included in the MicroLabBox platform.
