A single-phase single-stage six-switch dual-output split-source boost inverter

Abstract

The invention discloses a single-phase single-stage six-switch dual-output split-source boost inverter, which belongs to the technical field of power generation, transformation or distribution. The circuit includes: a booster circuit composed of a first inductor, a first MOS transistor, a second MOS transistor, and a first capacitor, a third MOS transistor, a fourth MOS transistor, a sixth MOS transistor, a seventh MOS transistor, and a first resistor A first output circuit composed of an inductive load, and a second output circuit composed of a fourth MOS tube, a fifth MOS tube, a seventh MOS tube, an eighth MOS tube, and a second resistive-inductive load. The structure of the whole circuit is simple, the input current of the power supply is continuous, and the input end uses a MOS tube instead of a diode to connect with the inverter bridge, which effectively avoids the problem of high frequency commutation of the diode. The circuit adopts fewer passive components, and enables the first output circuit to have a higher output voltage gain under the condition of ensuring that the second output circuit does not step down. The load current is continuous, and the first output circuit and the second output circuit can realize the same amplitude and same frequency, same amplitude and different frequency, different amplitude and same frequency, and different amplitude and different frequency output.

Description

technical field [0001] The invention relates to power electronic circuit technology, in particular to a single-phase single-stage six-switch dual-output split-source boost inverter, which belongs to the technical field of power generation, transformation or distribution. Background technique [0002] One of the trends that researchers follow when designing power converters is to reduce the number of passive and active components used, thereby reducing the overall cost of the converter. However, in different applications, to meet the increasing independent power supply requirements of AC loads, an independent inverter is usually configured for each load, but the use of independent inverters increases the number of switches such as IGBTs and MOSFETs, and drives The number of circuits and drive power supplies also increases, which can lead to unnecessary increases in system cost, size, and weight. [0003] To maintain high power quality and improve system reliability, topologi...
