ELECTRICAL SPECIFICATIONS
The maximum power and current capability of the system is dictated by the allowable
temperature rise of the different components. Establishing maximum limits is not simple
given the host of different ways the user may use the system. The voltage and the
nature of the electrical load used both affects the dissipation that occurs. In determining
the allowable limits for the power semiconductors, the following assumptions have
been made:
• Heat sink is at 70°C (worst case)
• Thermal resistance of the insulating thermal pad is 3°C/W

The system continuously operated during one hour, 15 kHz switching
frequency and the PFC boost circuit disabled.
It is possible to increase the available maximum output power up to
4000W by using an external ventilation mechanism attached to system
near to the power module. To provide additional air flow, a conventional
AC muffin fan can be used (Comair-rotron part number 028021 or
028023). An alternative bonded fin heat sink with fans attached is also an
option (C&H Technology, Inc. part number CH5117F).
The system continuously operated during one hour, 50 kHz switching
frequency.
It is possible to increase the available maximum output power up to
1400W by using an external ventilation mechanism attached to system
near to the PFC IGBT. To provide additional air flow, a conventional AC
muffin fan can be used (Comair-rotron part number 028021 or 028023).
An alternative bonded fin heat sink with fans attached is also an option
(C&H Technology, Inc. part number CH5117F).
