| Abstract: | The Zero Voltage Switch（ZVS）technology is widely used in the field of switch power. It ／ usefully takes advantage of all components in the circuit. Resonant makes high efficiency true. Moreover, the waveforms are very clean. The article uses HIP4081 as the drive chip. And design a single logic circuit to convert the PWM output signals into required phase shift drive signals. Thus, making the HIP4081 drive the full-bridge and work well. At last, we design and calculate the ZVS parameters to make a high efficiency DC to DC converter. |
