一种应用于无线输电系统的升压电路
摘要：
本发明公开一种应用于无线输电系统的升压电路，所述电路包括：原边电路、副边电路；所述原边电路包括电源、第一前置升压电感L1、第二前置升压电感L2、电流逆变器、第一电解电容Cc、LCL谐振电路；所述电流逆变器包括第一开关管Q1、第二开关管Q1a、第三开关管Q2、第四开关管Q2a；所述副边电路包括串联谐振电路、第一二极管D1、第二二极管D2、第三二极管D3、第五开关管Qs、第二电解电容Co以及负载。本发明中通过在原边设置前置升压电感，用于提供给电流逆变器由于开关管所需的软开关的电流，不需要现有技术中传统的全桥逆变器需要等效负载呈感性才能实现软开关。
摘要（英）：

The invention discloses a boosting circuit applied to a wireless transmission system. The circuit comprises a primary side circuit and a secondary side circuit. The primary side circuit comprises a power supply, a first pre-boosting inductor L1, a second pre-boosting inductor L2, a current inverter, a first electrolytic capacitor Cc, an LCL resonant circuit; The current inverter comprises a firstswitch tube Q1, a second switch tube Q1a, a third switch tube Q2, and a fourth switch tube Q2a. The secondary side circuit includes a series resonant circuit, a first diode D1, a second diode D2, a third diode D3, a fifth switching tube Qs, a second electrolytic capacitor Co, and a load. In the invention, a pre-boosting inductor is arranged on the primary side for supplying the current to the current inverter due to the soft switching required by the switching transistor, so that the conventional full-bridge inverter in the prior art does not need the equivalent load to be inductive so as to realize the soft switching.
