    Abstract: A power inverter control adjusts input power to track with output power to reduce energy handling requirements for an inverter DC bus. Input power to the power inverter circuit is measured and compared with a measurement of inverter output power. The comparison result is applied to a power factor correction circuit to adjust input power to track with output power, while obtaining a good power factor for the power inverter circuit. The energy requirements and ripple voltages or ripple currents on the DC bus are reduced, leading to a reduction in rating specifications for passive energy storage elements on the DC bus.

    Abstract translation: 逆变器控制器通过调节输入功率来跟踪输出功率,以降低逆变器直流母线的能量处理要求。 测量功率逆变器电路的输入功率,并与逆变器输出功率的测量结果进行比较。 比较结果应用于功率因数校正电路,以调整输入功率以跟踪输出功率,同时为功率逆变器电路获得良好的功率因数。 DC总线上的能量需求和纹波电压或纹波电流减少,导致DC总线上无源能源存储元件的额定值规格降低。
