A new topology of the high frequency alternating current (HFAC) inverter bridge arm is proposed which comprises a coupled inductor, a switching device and an active clamp circuit. Based on it, new single-phase and three-phase inverters are proposed and their operating states are analysed along with the traditional H-bridge inverter.
Modulation Techniques: Discover various modulation techniques employed in high-frequency inverters to control the output AC waveform. Applications of High-Frequency Inverters: Explore the vast range of applications for high-frequency inverters, including motor drives, renewable energy systems, and power grid integration.
In many applications, it is important for an inverter to be lightweight and of a relatively small size. This can be achieved by using a High-Frequency Inverter that involves an isolated DC-DC stage (Voltage Fed Push-Pull/Full Bridge) and the DC-AC section, which provides the AC output.
However, unlike ‘traditional’ grid-connected machines, such inverters inherently produce high-frequency, large-amplitude common-mode voltage waveforms, unless specific design measures are taken.
Our photovoltaic container solutions including 20ft/40ft containers, custom mobile containers, commercial and industrial energy storage systems are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
