Load Independent Class- E⁻¹Inverter with Shunt Capacitance

Load‐independent inverse class‐E ZVS inverter and its application to wireless power transfer systems

“…In ref. [18], the performance evaluations of the proposed inverter for $$D=0.5$$ are shown. The experimental results show the inverter achieved that the load‐independent mode, namely the CC and the ZVS at any load resistances, as predicted in the analysis.…”

“…During the switch OFF state, the pulsed voltage is generated at the switch as 1 Only the circuit topology and the experimental results for the case of D = 0.5 are shown in ref. [18]. In this paper, a new analysis of the load-independent ZVS inverse class-E inverter at any duty ratio is presented.…”

“…Figure 4(a) shows the power output capability as a function of the 𝜔C S R. From Figure 4(a), we can see that there are peak values of c p according to the duty ratio. Figure 4(b) shows the peak values of the power-output capability as a function of D. The maximum value of c p can be obtained at D = 0.52 and 𝜔C S R = 0.61.In ref [18],. the performance evaluations of the proposed inverter for D = 0.5 are shown.…”

“…The load-independent operation, which is a particular operating mode of the resonant inverter, has a possibility to solve the above problems. The load-independent class-E inverter [13][14][15][16][17][18] consistently achieves both the soft switching and the constant output current (CC) or constant output voltage (CV) at any load resistances. About 30 years ago, the first proposal for the load-independent class-E inverter was made [13].…”

“…This paper, which is the enlarged edition based on [18], 1 proposes the load-independent inverse class-E ZVS inverter with shunt capacitance. The proposed inverter explicitly incorporates the GaNFET drain-to-source capacitance into the circuit topology to achieve a new resonant structure with the shunt inductance.…”
