“…Among various topologies, totem-pole bridgeless PFC is attractive owing to its advantages of high device utilization and low conduction loss [11][12][13]. To further improve power efficiency, SiC MOSFET currently tends to replace Si MOSFET in power converters [14][15][16]. However, these improvements bring new challenges to PFC converters and their control strategy.…”

This paper explores a current distortion problem in totem-pole bridgeless power factor correction (PFC) converters with average current mode (ACM) control. With in-depth modeling for the current and voltage loops, it was found that the current distortion is caused by the limited current loop bandwidth and input filter capacitor. These factors lead to the presence of a susceptance component in the input admittance, which degrades the power factor (PF) and total harmonic distortion (THD) of the PFC converter. To solve this problem, this paper proposes virtual admittance feedforward compensation (VAFC) and phase correction methods to adjust the input admittance to pure conductance. The VAFC can generate virtual admittance that compensates for susceptance components in the input admittance, while phase correction can generate an equivalent current source that offsets the current in input capacitors. Furthermore, a phase lock loop (PLL) is introduced to realize the VAFC, which reduces the feedforward interference caused by input voltage sampling noise. Finally, an experimental prototype was built to verify the effectiveness of the proposed strategies. According to the test results, the proposed compensation strategy improves the PF by 1.23%, while reducing the THD by 2.52% and achieving a peak efficiency of 98.69%.

<div class="section abstract"> <div class="htmlview paragraph">The paper characterizes and documents the performance evaluation of an electric motor and motor controller/inverter. An overall energy balance on the electric motor itself was performed that resulted in a maximum operating efficiency of 94%, while the combined motor and motor controller/inverter system resulted in an 80% efficiency at 2,500 RPM and 60 Nm operating conditions. The zero load power requirements were identified across a span of operating conditions and compared against manufacturer provided values. Vibrations in the system were shown to impact motor control, through the current draw values, that resulted in unstable operation regimes.</div> </div>
