| Abstract: | The H-bridge soft-switch DC/DC converter is introduced including its driving level and time sequence.And the PWM control signal generator based on CPLD,with adjustable duty-cycle and switch delay time,is designed.It is programmed with VHDL language,and can also be used in H-bridge soft-switch DC/DC converter circuit.Compared with the special control chips,the design is flexible to adjust delay time,and convenient to interface with control unit. |
