“…1c presents the dc-to-dc FBSS resonant converter topology for a gate driver power supply function. The analysis of this resonant converter is organised as: series-series (SS) resonant tank modelling, voltage transfer ratio considerations, zero voltage switching (ZVS), frequency controllability of SS tank, capacitor compensation calculations, equivalent impedances, robust controller design are detailed in the previous publications [6,7,[22][23][24][25][26]. To achieve a high galvanic insulation system for MVDC (up to 50 kV), the air gap of the selected transformer must be between 0.5 and 3 mm [5].…”

“…Power switches such as metal-oxidesemiconductor field-effect transistor (MOSFET) and insulated gate bipolar transistor (IGBT) always require control systems called 'gate drivers' to perform accurate switching pulses transmissions. According to [5][6][7], the IGBT gate driver functions are ( Fig. 1a): (i) switching pulse-width modulation (PWM) signal transmissions, (ii) default information's transmissions, (iii) power supply transmissions ( Fig.…”

“…As a result, the compact ferrite core planar transformer achieves higher coupling ( k ) and inductors values than the coreless one. According to [6], ferrite pot core shape gives the best magnetic coupling compared with other geometries (U and toroidal core shapes). Thus, in this paper, the high insulation technology with high air gap pot core planar transformer is proposed.…”

“…In [6, 7], the authors have demonstrated that a power transmission function can be achieved with higher insulation voltage level than former paper [14]. However, some aspects such as the electrostatic modelling of a pot core planar transformer, material breakdown voltage testing, converter power density, and details about the optimisation design are not presented.…”

For the operation of the semiconductor components in medium voltage converter or multilevel converter applications (where the DC bus voltage up to several ten kilovolts), their gate driver systems require very high galvanic insulation voltage capabilities. Hence, this study details a design methodology to optimise a power supply function for insulated gate bipolar transistor gate drivers with high insulated voltage capabilities. To achieve this, a dc-to-dc full-bridge series-series resonant converter with a high air gap pot core planar transformer is selected. This air gap length and the dielectric material define the high insulation voltage capability. The objective of the study is to optimise the geometric elements of the transformer and its associated electrical components in the proposed converter. Magnetic and electrostatic modellings are provided. Maximise the converter efficiency (η con) is the main objective of the proposed optimisation design. Thus, the optimisation results are proposed: the converter efficiency (η con) as function of converter output power (P out). Finally, to validate the authors' proposed methodology, the experimental results are compared with the simulation ones. Then, the results of an improved optimisation design are provided.

The proposed study is about the design and experimental results of a power supply for gate drivers that can sustain 40 kV of insulation voltage with a parasitic capacitance of 4 pF. The first section focuses on insulation materials suitable for medium voltage capabilities and therefore to justify the use of polyesterimide and Teflon polytetrafluoroethylene materials. In a second step, experimental results are provided to guaranty that with a thickness of 1 mm of the insulation material, an insulation voltage of 40 kV is provided. Then, a DC-DC converter based on a series-series topology is designed and lead to a physical prototype of 5 W. The measured parasitic capacitance is 4 pF between the primary and the secondary sides.
