Thermal Consideration continued
Definition of reference temperature (Tref)
The reference temperature is used to monitor the temperature
limits of the product. Temperatures above maximum Tref are
not allowed and may cause degradation or permanent
damage to the product. Tref is also used to define the
temperature range for normal operating conditions.
Tref is defined by the design and used to guarantee safety
margins, proper operation and high reliability of the module.
Ambient Temperature Calculation
By using the thermal resistance the maximum allowed
ambient temperature can be calculated.
1. The power loss is calculated by using the formula
((1/η) - 1) × output power = power losses (Pd).
η = efficiency of converter. E.g 89.5 % = 0.895
2. Find the thermal resistance (Rth) in the Thermal Resistance
graph found in the Output section for each model.
Calculate the temperature increase (ΔT).
ΔT = Rth x Pd
3. Max allowed ambient temperature is:
Max Tref - ΔT.
E.g PKL4118B PIT at 2m/s:
1. ((
) -
1) × 144 W = 25.0 W
2. 25.0 W × 1.3°C/W = 32.5°C
3. 110 °C — 32.5°C = max ambient temperature is 77.5°C
The actual temperature will be dependent on several factors
such as the PCB size, number of layers and direction of
airflow.
