Analysis and design of loosely coupled power supply based on the class E amplifier
摘要
Abstract
The design of the loosely coupled power supply is based on class E power amplifier circuit , and its circuit topology is analyzed in this paper .We analyze this modified circuit by decoupling equivalent model , and divide the circuit into four working states , solve it in time-domain and draw the theory waveform respectively .By analyzing the relationship that the circuit frequency changes with the coupling coefficient and switch -on time of the MOSFET , as well as analyzing the relationship between output power and switch-on time of the MOSFET , we propose a kind of pow-er control strategy-switch on the MOSFET when the current is zero-crossing and control the switch-on time by the aver-age current .This strategy can stabilize the power output , and experimental verification is conducted in the last .关键词
