    • A power converter enhances conversion efficiency from DC power to AC power. A first chopper circuit chops DC voltage from a photovoltaic panel at a system frequency producing a first square-wave whose voltage level changes positively. A second chopper circuit chops the first square-wave at a frequency double the system frequency producing a second square-wave whose voltage level changes negatively and adds the first square-wave and the second square-wave to produce a third square-wave that changes positively and negatively in a sine-wave manner. A third chopper circuit charges and discharges by chopping the third square-wave at a third frequency fixed by timing according to a difference between the third square-wave and a sine-wave voltage. PWM control is performed on the charge and discharge outputs such that the difference is corrected, producing a sine-wave voltage that continuously changes positively and negatively. A spike noise of an output voltage is suppressed.
    • 电源转换器提高从直流电源到交流电源的转换效率。 第一斩波电路以系统频率从光伏面板切断直流电压,产生电压电平正向变化的第一方波。 第二个斩波电路以一倍于系统频率的频率斩波第一个方波,产生一个第二个方波,其中电压电平发生负变化,并加上第一个方波和第二个方波,产生一个第三个方波 以正弦波方式积极和消极。 第三斩波电路通过根据第三方波和正弦波电压之间的差定时固定的第三频率斩波第三方波进行充电和放电。 对充放电输出进行PWM控制,使得差异被校正,产生正负不断的正弦波电压。 抑制输出电压的尖峰噪声。
