A synchronous motor differs from an asynchronous motor in the relationship between the mechanical speed and the electrical speed. In a synchronous motor, the supplied voltages have the same frequency as the mechanical motor speed. In an
Calculation of Power Loss (Synchronous) : Power Management
fscdn.rohm.comCalculation of Power Loss (Synchronous) This application note describes how to obtain the power loss required to calculate the temperature of a semiconductor device. Temperature control is important to ensuring product reliability. Figure 1 is a circuit diagram of a synchronous rectification type DC/DC converter. Figure 2 shows a switching node ...
