Resonant radio energy transmitting device with PFC (power factor correction)
A resonant radio and transmitting device technology, applied in the direction of circuit devices, output power conversion devices, electrical components, etc., can solve the problem of not considering the input power factor of the power supply, the input of the transmitting device is not isolated from the DC power supply, and increase the wireless energy. Problems such as the size of the transmission and emission device, to achieve the effect of fewer power devices, less pollution, and higher efficiency

Problems solved by technology
 Such as figure 1 Shown: a resonant wireless power transmission transmitter with PFC, including a single-phase PFC link, a DC-AC converter link and an output resonant network, the DC-AC converter link is connected in parallel between the PFC link and the output resonant network between networks.
 The single-phase PFC link consists of a rectifier bridge, an input inductance L 1 , the first MOS tube S 1 , Diode D 5 and output filter capacitor C o Composition, to realize the correction of input power factor;
 The DC-AC converter link consists of a high-frequency transformer T and a second MOS transistor S 2 Composition, to realize the exchange of DC to AC;
 The output resonant network consists of a resonant inductor L 2 , Resonant capacitance C 2 And the equivalent load R constitutes.
 The equivalent load R is the load reflected from the wireless power transmission receiving end to the transmitting end.
 The rectifier bridge...
