This paper proposes an independent/grid connected duplex mode inverter system for photovoltaic inverter systems. EI803F 3BDH000017R1 analyzes the inverter topology and control principle, improves it with feedforward control, proposes a method for switching between two working modes, and develops an experimental prototype to verify its feasibility. The results show that the inverter system developed by this scheme works stably, runs reliably, can work in both independent and grid connected modes, and can switch freely. The system has good application prospects.

Direct conversion receiver, also known as zero IF receiver, EI803F 3BDH000017R1 is widely used in various communication and instrumentation applications. People seem to be increasingly hoping to push the filter bandwidth to the Nyquist boundary in direct down conversion. The motivation behind the requirement to utilize all Nyquist bandwidth of analog-to-digital converters (ADCs) is to reduce power consumption, alleviate heat issues in increasingly dense packaging, lower costs, and extend backup time or battery life. In this article, we will explore some of the challenges and concerns faced by this type of design, and compare direct conversion with intermediate frequency sampling (IF sampling) when the signal bandwidth is close to 100MHz.
