High efficiency boost converter power supply reference design for automotive DC/AC inverter

This single-phase boost converter operates over an input voltage range of 120 V - 350 V and provides a non-isolated output of 221 V / 0.87 A. Input voltages above 221 V are passed through to the output. With an efficiency of greater than 97%, component losses are reduced, which results in lowers (...)
