Beschreibung
Zusammenfassung:	The utility model discloses a photovoltaic power generation device with auxiliary resonant circuit, including photovoltaic array, boost boost circuit, auxiliary resonant circuit, PWM contravariant bridge, three phase resistance inductive loads. Boost boost circuit realizes that photovoltaic array output maximum power trails, through auxiliary resonant circuit's resonance, switching, voltage and electric current zero lap during the power device switch are accomplished to PWM contravariant bridge switching element under the no -voltage condition. The utility model discloses direct current side voltage can periodically drop to zero, makes the switching element of PWM contravariant bridge realize zero voltage switch, is favorable to reducing photovoltaic power generation's switching loss, improvement switching frequency, is showing the efficiency that has improved photovoltaic power generation.
