Abstract
The subject apparatus and method measures the Total Average Power Loss and isolates the different power loss components of Total Average Loss such as TLoss and Tloss at switching devices such as, MOSFETs, BJTs and IGBTs that may be used in a switching power supply. It provides separation of the components of Total Average Loss as Turn Ton Loss, Turn Toff Loss and allows derivation of conduction loss. It also has the capability to measure Total Average Loss and Switching Loss, while amplitude, duty cycle and frequency of the switching signal is varying in a switching power supply.
