Key relationships to be considered are the following: 1. Transfer Function a. No load condition VOUT = VIN • K Eq. 1 Where K (transformer turns ratio) is constant for each part number b. Loaded condition VOUT = Vin • K – IOUT • ROUT Eq. 2 2. Dissipated Power The two main terms of power losses in the BCM module are: - No load power dissipation (PNL) defined as the power used to power up the module with an enabled power train at no load. - Resistive loss (ROUT) refers to the power loss across the BCM modeled as pure resistive impedance. PDISSIPATED ~ PNL + PR OUT Eq. 3 ~ Therefore, with reference to the diagram shown in Figure 15 POUT = PIN –PDISSIPATED = PIN –PNL –PR OUT Eq. 4 Notice that ROUT is temperature and input voltage dependent and PNL is temperature dependent (See Figure 15). INPUT POWER OUTPUT POWER PNL PR OUT Figure 15 – Power transfer diagram The above relations can be combined to calculate the overall module efficiency: η = POUT = PIN –PNL –PR OUT = PIN PIN VIN • IIN –PNL –(IOUT) 2 • ROUT =1 – (PNL+ (IOUT)2•ROUT) VIN • IIN VIN • IIN Eq. 5 Not Recommended for New Designs |
