Can a step-down DC-DC converter be used as an inverter?
When using a step-down DC-DC converter as an inverter, there are some limitations. The voltage difference between the input and the negative output must be less than the step-down DC-DC converter's maximum operating input voltage. In essence, a step-down DC-DC converter with maximum input of 12V can be used to convert 5V to -7V, but not more.
How does an existing inverter provide stepped-down voltage?
In the existing inverter, the voltages of the main capacitors C 1 and C 2 are averaged by connecting the flying capacitors C 3 and C 4 to C 1 or C 2 alternately. Thus, the existing inverter provides the stepped-down voltage (1/2) × V i n alternately to V o 1 and V o 2 without a full-bridge circuit.
Does a single-phase inverter provide a stepped-down AC voltage?
By changing the connection order of series-connected capacitors alternately, the proposed single-phase inverter provides a stepped-down ac voltage. The advantages of the proposed single-phase inverter are inductor-less design, downsizing by omitting flying capacitors, no full-bridge design, and symmetrical topology.
What is an inverting power supply using a synchronous step-down regulator?
This application report discusses creating an inverting power supply using a synchronous step-down regulator. The design generates a negative voltage from a positive input voltage. Applications that often require an inverted output voltage from a positive input voltage are those with amplifiers and data converters.
Can a step-down inductor-less inverter provide a stepped-down AC voltage?
In this paper, a novel step-down inductor-less inverter is designed by using SC techniques. By changing the connection order of series-connected capacitors alternately, the proposed single-phase inverter provides a stepped-down ac voltage.
How efficient is a stepped-up inverter?
When the output power is 200 W, the proposed inverter can achieve about 83% and 93% efficiency in the step-up mode and the step-down mode respectively. Table 3 illustrates the comparison result. As Table 3 shows, unlike the conventional inverter, the proposed inverter can provide not only stepped-up voltage but also stepped-down voltage.
Featured Solar Products

They have a higher efficiency in converting sunlight into electricity compared to other types of panels. Their sleek appearance also makes them a popular choice for both residential and commercial installations. Moreover, they are durable and can maintain stable performance under various environmental conditions, ensuring a long lifespan and excellent return on investment.
High - Capacity Lithium - Ion Energy Storage Systems
Our high - capacity lithium - ion energy storage systems play a crucial role in optimizing solar energy usage. Utilizing state-of-the-art lithium-ion battery technology, they can store a significant amount of energy generated by solar panels during the day. This stored energy can then be used during peak demand periods or when sunlight is insufficient, such as at night or on cloudy days. With features like high energy density, fast charging, and long cycle life, these systems provide a reliable and efficient solution for energy storage, enabling you to achieve greater energy independence.
Smart Hybrid Inverters
Smart hybrid inverters are the key to a seamless and intelligent solar power system. They can intelligently manage the flow of electricity between solar panels, energy storage systems, and the electrical grid. These inverters not only convert the direct current (DC) from solar panels into alternating current (AC) for household or business use but also optimize the charging and discharging of energy storage systems. With built-in monitoring and communication features, you can remotely control and monitor your energy system, making it easy to adjust settings and track performance.
Portable Solar Power Stations
Portable solar power stations are designed for on-the-go power needs. They integrate solar panels, energy storage, and inverter functions into a single, lightweight unit.

Their portability and ease of use make them a convenient choice for anyone who wants to access clean energy wherever there's sunlight, providing a reliable power source in remote locations or during power outages.
Distributed Photovoltaic Power Station Solutions
Our distributed photovoltaic power station solutions are tailored for various applications, from small communities to large industrial complexes. By distributing solar panel installations across multiple locations, we can make better use of available space and increase the overall energy generation capacity. These solutions are designed with high-performance components and integrated monitoring systems to ensure efficient operation, easy maintenance, and maximum energy yield. They also contribute to reducing the reliance on the main power grid and have a positive impact on the environment.
Micro Inverters
Micro inverters offer a unique advantage in solar power systems. Unlike traditional string inverters, each micro inverter is connected to a single solar panel, allowing for individual panel optimization. This means that even if one panel is shaded or has a lower performance due to some reason, it won't affect the overall output of the entire system. They are easy to install, highly efficient in converting DC to AC power, and provide better flexibility in system design, making them suitable for both residential and small commercial solar installations.
Roof - Integrated Photovoltaic Power Stations
Roof - integrated photovoltaic power stations combine the functionality of solar power generation with the aesthetics of building design. These stations are custom-designed to fit directly onto rooftops, replacing traditional roofing materials in part or in whole. They not only generate clean energy but also enhance the overall look of the building. With advanced installation techniques and durable materials, they can withstand the elements while providing a long-term and reliable source of electricity, making them an ideal choice for both new construction and retrofit projects.
Transformer Selection for Grid-Tied PV Systems
In this scenario, the PV system is exporting power to the grid. The transformer will need to accommodate, e.g. step down the voltage: from 480 V along the inverter circuit to provide 208 V to the utility side circuit. In this context, the transformer will be energized first from the utility side, and the inverter side second.
