The total power losses can be determined through the equation below:
where:
Pe = power losses at the electronics (W)
tc = working cycle time (s)
Ip = start current (A)
tp = start time (s)
In = current at rated duty (A), with By-pass In=0
tr = rated duty time (Full Voltage) (s)
Ptd = total power losses (W)
