Converter design and control

EELAB has been designing and building power electronic converters from before 1980, which means that a lot of expertise is available to design or analyse power electronic converters in a wide range of applications: ac-dc converters with power factor correction, high-efficiency dc-dc converters, inverters for motor drives. The key issues are:

  • For the control of these converters, we have experience with analogue control as well as with digital control. 
  • Concerning gate drives, several generations have already passed. The first was to obtain good dv/dt immunity of fast rising edges and incorporation desaturation protection, faster drives with higher accuracy and incorporation more measurement possibilities. Now there is a tendency to gate drives with low power consumption, high reliability and small parasitic capacitance. 
  • Special attention was given also to good layout of power stages having very low parasitic inductance.
  • There is also research how to improve the robustness of internal power supplies for power electronics and how to reduce the stand-by losses of supplies for power electronics.
