GvA Leistungselektronik: 3D Konstruktion eines 3-Phasen Wechselrichters Where complex and lengthy investigations and simulations go beyond the scope of well founded consultation, GvA Leistungselektronik GmbH offers engineering services for power semiconductor applications.

Regardless of whether it involves series or parallel operations - or chip temperature calculations for repeated intermittent operation at varying load currents, GvA Leistungselektronik GmbH can quickly deliver a well founded and correct result. Our expertise is based on decades of experience in working with power semiconductors. Using the newest simulation software available our goal-oriented support helps your development team achieve results faster.

Our engineering services encompass the following thematic areas:

  • electrical and thermal dimensioning of power semiconductors
  • related mechanical construction
  • dimensioning of protective circuits
  • dimensioning of power semiconductor driver stages
  • optimisation of existing developments
  • determining the cause of failures
  • investigation of heat sink thermal properties over time
