Part II of this series expands on the previous material. The non-ZVS PSFB has switching power dissipation peaks which are 5 times higher than the plain full bridge SMPSthis appears to confirm that the PSFB, when in non-ZVS behaviour, has far higher switching loss than the plain full bridge. Typically the output produced is at a different voltage level than the input. The dsPIC33F "GS" family series of Digital Signal Controllers (DSCs) was introduced by Microchip Technology Inc. The MOSFETs are driven through a small transformer that itself is driven with a H-bridge. The linear regulator regulates a continuous flow of current from the input to load in order to maintain a constant load voltage. Following the front end stage of an AC/DC rectifier, a DC/DC power converter is required to step down the bus voltage and provide a galvanically isolated and tightly regulated DC output (eg.
