It seems that the average of ee_getPowerLossTimeSeries is equal to 'Power' of ee_getPowerLossSummary.
Estimate Power losses of a Simscape Model

I have an inverter made of three Half-bridge (ideal, switching) Blocks and I want to estimate the overall losses and the losses vs. time.
The function ee_getPowerLossSummary(simlog); returns two values and I am not sure how to interpret them. Does the column 'Power' represent the total losses (switching and R*I^2 losses)? In other words, if I subtract the column 'SwitchingLosses' from 'Power,' is the result the R * I^2 loss of the component?
My second question is regarding the function ee_getPowerLossTimeSeries(simlog);
Lets say I want to calculate the overall losses just from the result of that function. If I integrat the losses via 'trapz' I get the overall loss energy. That divided by the simulation stop time should result in the total losses of the component and should be equal to the result of ee_getPowerLossSummary(simlog); But in my case it isn't. I'm unsure about my approach. Can you pinpoint where I might be going wrong?
My approach for Half_bridge_A results in 0.2700 W, below the result of PowerLossSummary is shown:
