This paper proposes a common-mode electromagnetic interference (CM-EMI) spectrum calculation method based on double Fourier series for photovoltaic (PV) inverters with chaotic sinusoidal pulsewidth modulation (CSPWM). In this paper, the CM-EMI of a single-phase PV inverter is first analyzed, and the equivalent circuit of the CM-EMI in the single-phase PV inverter is established, then the CSPWM is...
The well established advantages of resonant converters for battery chargers, including fast response, low switching losses, easy of the control scheme, simplicity of circuit configuration, and low electromagnetic interference (EMI), among others, have led to their increasing attraction. This work develops a highly efficient battery charger with a parallel-loaded resonant converter for battery charging...
