| 摘 要： | 针对高频感应加热电源中用传统的模拟锁相环跟踪频率所存在的问题,提出一种非常适合于高频感应加热的新型的数字锁相环。使用FPGA内底层嵌入功能单元中的数字锁相环74HCT297,并添加少量的数字电路来实现。最后利用仿真波形验证该设计的合理性和有效性。整个设计负载范围宽、锁相时间短,现已成功应用于100 kHz/30 kW的感应加热电源中。

| Abstract: | Aiming at the disadvantage of the traditional analog PLL in the high frequency induction heating power supply.A new digital phase locked loop is proposed.It is especially applicable for high frequency induction heating power supply.It is based on 74HCT297 which is integrated in FPGA tools,and add some digital-circuit for it.In the end,using emulation mode to verify the available of the new PLL.This design can be applied to a wide-range of loads.And time is short to lock phase.This new PLL is used in 100 kHz/30 kW high frequency induction heating power supply. |
