Power Semiconductor Parameteric Analysis

AMCAD Engineering's High-Voltage BILT Pulsed IV (Pulsed DC, Pulsed Bias) Systems

Introduction

AMCAD Engineering has expanded its industry-proven pulsed IV system (Pulsed IV, PIV, parametric analysis) for high-voltage power conversion applications. The system is ideally designed specifically for medium- and high-voltage Gallium Nitride (GaN) technologies used in automotive (hybrid cars), alternative energy, industrial computers... applications. Systems come fully equipped with a common 19" rack mountable mainframe controller which includes five integrated power supplies, standard gate pulse head, and 1000V/30A drain pulse head. The system is driven by Maury's MT930-series IVCAD measurement and modeling device characterization software.

Pulsed IV system for high-voltage power conversion applications

Key Features

  • High-power 1000V, 30A pulse generation
  • Pulse width down to 400ns
  • High precision current and voltage measurement
  • Embedded fast short-circuit current breaker, performing the protection of the internal probe circuitry at device breakdown
  • Embedded fast measurement samplers:
  • Fast average and ripple acquisition for highest signal to noise ratio, 16 bit compliant
  • Pulse shape monitoring equivalent to a 50M sample/s scope, 8 bit resolution
  • Pulse and measurement clocks are both available in stand alone or external triggered mode
  • Ideal for GaN, SiC, MOSFET and IGBT technologies
  • Designed for power conversion applications: automotive (hybrid cars), alternative energy, industrial computers, etc.
