“…But, as also stated in [29], the main contributors to the overall losses with IGBT applications are the turn-OFF losses. According to [30] and [31] the main reason is that these semiconductors are characterized by a bipolar power stage, that, in order to block HV, comprise a considerable large N-base region, which stores a large amount of charge during the conduction phase of the semiconductor. When the switch is turned off, this stored charge is evacuated from the semiconductor, causing tail currents that overlap with the blocking voltage, generating high switching losses.…”

This paper is introducing a new method of operation for a series resonant converter, with intended application in megawatt high-voltage DC wind turbines. Compared to a frequency controlled series resonant converter operated in sub resonant mode, the method (entitled pulse removal technique) allows the design of the medium frequency transformer for highest switching frequency, while being operated at lower frequency without saturation. The main focus of this paper is to identify and analyse the operating modes of the converter with pulse removal technique. With the use of variable frequency and variable phase displacement in sub resonant mode, the new method of operation promises transformer size reduction and facilitates soft-switching transition of the IGBTs and line frequency diodes on rectifier side. Four modes of operation are identified, while equations for output power, voltage and current stress are identified. Experimental results are concluded on a 1 kW, 250V / 500V prototype.

“…Not only in standard industry converters or medium voltage drives but also in traction converter systems like the Medium Frequency (MF) topology [12], [13], [14] the robustness and reliability of GDUs is essential for the system's reliability and thus availability. This is due to the high number of power switches in such systems.…”

In recent years a tendency to increase the number of semiconductor switches in power electronic systems can be observed. This changes the requirements of modern gate units, which are forced to become more simple and reliable. Nevertheless, the performance of the switches should not be affected. This paper presents a review of the state of the art for GDUs. Since existing driving methods are often far too complex and expensive for modern PE-Systems (e.g. power electronic traction transformer etc.), a new simple Dual Stage Driver GDU with fixed timing control is proposed to reduce the IGBT turn-on losses. A detailed analysis of the timing dependency of important switching characteristics is given for every operating point to verify this method.

“…In SST applications, where voltage regulation is not compulsory [9], half-cycle discontinuous-conduction-mode SRC (HC-DCM-SRC) is an interesting option [7], [9], [10], since it accomplishes ZCS for both primary and secondary converters. Nevertheless, as discussed in several papers [7], [11], ZCS in primary switches is not free of switching losses. Hence, a minimum current during the switching process is necessary.…”

Many thriving applications where isolation is required, such as traction and EV fast charging, implement solid-state transformers (SST). Half-cycle discontinuousconduction-mode series resonant converters (HC-DCM-SRC) are suitable for these applications. The focus of this paper is to perform a comprehensive approach to HC-DCM-SRC and provide straight-forward requirements in order to ensure zeroloss switching (ZLS) of semiconductors. In addition, these requirements can be expressed as design boundaries for the transformer. Finally, the paper shows that, due to ZLS, silicon devices may have larger power capability than silicon-carbide switches. Therefore, IGBTs can be used instead of SiC MOSFETs, resulting in a significant cost reduction of the converter.
