Power Loss Calculation Software
When the Load Type specified in the Conditions is “Inductive”:
When the Load Type is “Resistive”:
• Driving Loss
Shows the driving loss as the calculation result.
This is calculated from the following expression.
• Total Power Loss
Shows the total sum of the conduction loss, switching loss, and driving loss.
b. Trend Chart
Shows the loss data for the swept parameter values as the calculation result in the
trend chart format. Where, the sweep parameter is assigned to the data for the
X-axis, and the conduction loss, switching loss, and driving loss are assigned to the
data for the Y-axis and are accumulated in this order.
You can change the minimum and maximum values on the X and Y-axes by clicking
the value.
