| description | The invention provides a zero voltage switch full-bridge direct-current converter with a diode and an auxiliary transformer clamping. In the invention, mainly based on a full-bridge direct-current converter comprising a direct-current power supply Vin, a first contravariant bridge arm, a second contravariant bridge arm, a resonance inductor, a clamping circuit, an isolation transformer and a rectification and filtering circuit, an auxiliary transformer and an auxiliary clamping circuit are added. The auxiliary transformer can effectively reduce current flowing over a lamping diode and an auxiliary clamping diode and improve working environment of the clamping diode; and meanwhile, since the clamping circuit and the auxiliary clamping circuit are both reversely connected in parallel at the two ends of input voltage of the converter, the converter can not be influenced by output voltage in a starting state or an output short-circuit current-limiting state at all; and therefore, the converter can use the voltage |
