摘要：
This paper presents a method for power loss analysis applied on single-phase grid-connected PV inverter. The often neglected current ripple effects are included in power device switching and conduction losses. The relationships amongst component losses, output inductance, switching frequency and dc-link voltage are investigated. It is shown that current ripple effect is important to power loss analysis due to varying irradiation. The closed form solutions of component losses are proposed and verified with SPICE simulation results.
