Load-Independent Class-E Inverter with Frequency-Modulation Control <Abstract> This paper proposes the frequency-modulation controlled load-independent class-E inverter. The main idea is to apply the frequency-modulation control of the output-voltage regulation to the load-independent class-E inverter, resulting in the fixed phase shift between the driving signal and the output voltage. As a result, the proposed inverter can maintain the constant output voltage and high power-conversion efficiency operation despite the load variations and the component tolerance in the output-resonant filter. The theoretical and experimental results showed the validity and effectiveness of the proposed inverter. |
