Beschreibung

This reference design presents an extremely compact auxiliary power supply with a combined output power up to 6 W. Three different isolated bipolar output voltages are provided: +15 V / -4 V, +19 V / -4 V and +20 V / -5 V. The design is optimized for driving high-voltage SiC-MOSFET and IGBT discrete devices as well as power modules in high-power converters, and can be easily integrated in the gate driver system. The extremely low interwinding capacitance of the WE-AGDT transformers down to 7 pF helps to achieve high CMTI rating (Common-Mode Transient Immunity). This enables fast switching speeds which can yield efficiency and power density gains, as increasingly required in trending applications in e-mobility,renewable energy or industrial automation.

Eigenschaften

  • Small size(Var.A: 27 mm x 14 mm x 14 mm) (Var.B: 40 mm x 14 mm x 13 mm)
  • 4 kV primary-secondary isolation
  • Only 7 pF typ. parasitic capacitance enabling high CMTI
  • PSR Flyback topology with LT8302 (ADI Power by Linear)
  • Load/line regulation less than 1 % typ.
  • Up to 88 % peak efficiency (86 % at 6 W)
  • Standard and AEC-Q qualified component assembly variants
  • Two PCB Layout Variants (2-layer and 4-layer)

Typische Anwendungen

  • Industrial drives: AC motor inverter
  • E-mobility: Electric Powertrain
  • Switch-mode power supplies with SiC MOSFETs
  • Renewable energy: Solar inverters
  • On-board and Off-board battery chargers
