增加元件集成度对于新的电源电路平台降低成本和尺寸、提高效率和可靠性至关重要。采用两片新型专用集成电路(ASIC)搭建了一台300W四象限(4Q)光伏并网微型逆变器，并对其进行了特性分析。该逆变器集成了最大功率点跟踪功能，并根据电网电压在0.9至0.9滞后的功率因数范围内动态运行，以符合加州电气委员会(CEC)第21条的要求。逆变器的CEC加权效率高于95.5%。总需求失真小于2%，最高可达39次。
Increased component integration is essential for new power circuit platforms to decrease cost and size, and increase efficiency and reliability. A 300 W four quadrant (4Q) photo-voltaic grid-tied micro-inverter using two new ASICs (Application Specific Integrated Circuits) was built and characterized. This inverter incorporates maximum power point tracking and dynamically operates throughout a power factor range of 0.9 leading to 0.9 lagging, based on grid voltage, to comply with the California Electrical Commission's (CEC) rule 21 requirements. The CEC weighted efficiency of the inverter is higher than 95.5%. Total demand distortion is less than 2% up to the 39th harmonic.
