本申请提供一种转换电路、转换器和电子设备,该转换电路主要包括原边电路、第一副边电路、第二副边电路和变压器。其中,第一副边电路包括第一整流电路、打嗝burst开关和续流电路,burst开关的输入端与第一整流电路连接,burst开关的输出端与续流电路连接。第一整流电路可以将第一交流电能转换为第一直流电能。burst开关可以在第一副边电路的输出电压不大于目标输出电压时导通,以使续流电路逐渐升高第一副边电路的输出电压;在第一副边电路的输出电压大于目标输出电压时断开,以使续流电路逐渐降低第一副边电路的输出电压。采样该实现方式可以在不影响第二副边电路的情况下,降低第一副边电路的输出电压。
The invention provides a conversion circuit, a converter and electronic equipment. The conversion circuit mainly comprises a primary side circuit, a first secondary side circuit, a second secondary side circuit and a transformer. Wherein the first secondary side circuit comprises a first rectifying circuit, a hiccup burst switch and a follow current circuit, the input end of the burst switch is connected with the first rectifying circuit, and the output end of the burst switch is connected with the follow current circuit. The first rectifying circuit can convert the first alternating-current electric energy into first direct-current electric energy. The burst switch can be switched on when the output voltage of the first secondary side circuit is not greater than the target output voltage, so that the follow current circuit gradually increases the output voltage of the first secondary side circuit; and when the output voltage of the first secondary circuit is greater than the target output voltage, the freewheeling circuit is switched off, so that the output voltage of the first secondary circuit is gradually reduced by the freewheeling circuit. By sampling the implementation mode, the output voltage of the first secondary circuit can be reduced under the condition that the second secondary circuit is not influenced.
