resonant capacitance
Examples
- By compared with the simulation results and the experiment results , we come to the conclusions that : ( 1 ) circuit with assistant network can widen soft - switching extent in lagging arm , reduces duty - cycle loss on the secondary , diminishes switching dissipation of inverter spot - welding power source . ( 2 ) the range of resonant capacitor , the important factor to soft - switching process , not only affects zero - voltage turn - off of power switches , but also affects the range of zero - voltage turn - on of power switches . so resonant capacitors must be considered according to many aspects ; ( 3 ) it easily fulfils soft - switching condition in lagging arm as leakage inductance of power transformer increases , but bigger leakage inductance of power transformer increases opening dissipation of transformer and decreases efficiency of soft - switching inverter power source
通过仿真结果与软开关点焊逆变器试验结果的对比分析，得到了如下主要结论：采用辅助网络可以完全拓宽全桥软开关逆变器的滞后桥臂软开关范围，减小了次级占空比丢失，降低了逆变电阻点焊电源的开关损耗；谐振电容是影响软开关工作状态的重要因素，其大小不仅影响开关管的零电压关断，同时也影响开关管的零电压开通范围，因此，谐振电容应该综合考虑；功率变压器漏感越大，越容易满足滞后桥臂的软开关条件，但是大的漏感也使变压器的通态损耗增加，降低了软开关逆变器的效率。 - A lcc multi - resonant ( mr ) network is added to the traditional three - level converters to realize zvs . the unique arrangement of a multi - resonant network results in absorption of all major parasitic components hi the resonant circuit , such as transistor output capacitance , diode junction capacitance and transformer leakage inductance , which can eliminate parasitic oscillation in the converter
