“…Depending on the type of power device and how many tasks should be performed on the submodule level [2], the amount of required power ranges from hundreds of milliwatt to a few watt [3]. Regarding the controllability, data integrity is of utmost importance, but the required data rate is not particularly high.…”

In this paper, power-over-fiber technology is used for combined power and data transfer applying amplitudemodulated light representing a pulse-width modulated signal that could be used for control of, for instance, power semiconductor devices in high-power converters. Even though the concept is generally applicable, an experimental verification aiming for a gatedriver of a switch in a modular multilevel converter is presented. In order to achieve a good resilience against electromagnetic noise, a concept where the modulated light is demodulated as a comparably powerful current signal is employed. A 5 MHz boost converter steps up the voltage to 15-20 V, such that silicon or silicon-carbide based power devices could be controlled. From the results, it can be concluded that it is possible to achieve transmission of a control signal with a latency of less than 500 ns for a gate drive unit of a high-power converter. The concept can easily be scaled up to powers of several watt.

“…Due to the requirement of communication at all times and control of other secondary functions, the need for power in the SM is critical. Because of it, solutions based on the SM bus to supply the auxiliary circuits, such as the ones proposed in [12] and [13], are out of choice. Then, it is concluded that an external source is required.…”

This paper presents an insulated auxiliary power source with multiple outputs based on a two-stage structure, where the first-stage operates as a controlled current source and the second-stage as an active rectifier. The second-stage is replicated for each load, where the output voltage is independently controlled by a hysteresis band controller integrated to the auxiliary power source's circuit. Insulation between the multiple stages is achieved by a medium-frequency transformer for each output. The main aim of this auxiliary power supply is to feed modular multilevel converters in laboratory applications that run at the lower range of medium-voltage dc. Theoretical analysis of the auxiliary power supply is presented and verified experimentally for the converter's two main modes of operation.

“…Compared to the full-bridge topology-based inverter (FBI), the WJI possesses merits of ease of driving (dual low-side switch), low power loss (working in synchronous mode), nonpulsating terminal currents, dead-time non-necessity, and simple control strategy. [12], therefore it is necessary to discuss whether it can be low-side-ized. …”

Abstract:The full-bridge topology is generally used in the post stage of inverter, to realize dc-ac voltage conversion. Inherent shortcomings of full-bridge such as high-side switch driving, prone to shoot-through and substantial power loss are inevitable. A topological solution is proposed in this letter, by means of improving the original coupledinductor Watkins-Johnson topology into dual low-side switch version and conducting synchronous control. Theoretical analysis and experimental results indicate that the improved topology is capable of generating pure sinusoidal ac output. The merits include ease of driving, low power loss, nonpulsating terminal currents, immunity to shoot-through, simple control strategy and so forth.
