摘要
运用松耦合变压器互感电路模型,推导出无接触电能传输系统原、副边分离的等效电路。选取合适的副边补偿电容,以增强系统的功率传输能力;选取合适的原边补偿电容,以降低对系统电源容量的需求。研究表明:当原边电流恒定时,在副边串联补偿,则负载所获取功率与负载大小成反比;在副边并联补偿,则负载获取功率与负载大小成正比。当原边电压恒定时,在原边并联补偿方式下,等效负载所获取的功率随负载的增加先升高后降低,针对不同的副边补偿方式,等效负载分别在相应的负载点取得最大传输功率。Pspice仿真结果验证了上述结论的正确性。
Equivalent circuits of contactless power transfer system with separated primary and secondary sides are deduced based on loosely coupled mutual inductance transformer model. Select appropriate compensating capacitance for secondary coil to enhance power transmission capability, and select appropriate compensating capacitance for primary coil to decrease system power capacity demand. Research shows that,when the primary current is constant,the load power is in inverse proportion to its magnitude with serial compensation at secondary side and is in direct proportion to its magnitude with parallel compensation at secondary side;when the primary voltage is constant and with parallel compensation at primary side,the load power increases first then decreases along with load increase and the peak point is different according to the compensation mode at secondary side, which are verified by Pspice simulation.
