Beschreibung
Zusammenfassung:	The utility model discloses a novel parallel resonance no -voltage photovoltaic power generation device, including photovoltaic array, boost boost circuit, auxiliary resonant circuit, PWM contravariant bridge, three phase resistance inductive loads. Through adding auxiliary resonant circuit between boost boost circuit and PWM contravariant bridge, make direct current side energy -storage capacitor voltage periodically return to zero, realize PWM contravariant bridge switching element and accomplishes switchings under the no -voltage condition that the switching element among the auxiliary resonant circuit can be realized also that the no -voltage is opened and turn -offs with the zero current moreover, is favorable to reducing and improvement switching frequency of switching element loss, has improved photovoltaic power generation's efficiency, when high switching frequency, can the volume of resonant inductance in the device do littleer, be favorable to the miniaturization of device, and then be applicable to high switching frequency's occasion.
