Journal Updates: Boost Soft-switching Converter

 

In order to improve the circuit working efficiency of zero-voltage zero-current transition Boost converter, an improved modulation strategy was proposed. The main switch can only achieve zero-current turn-on under traditional modulation strategy. Zero transition PWM circuit, including zero-current transition PWM circuit and zero-voltage transition PWM circuit, is applied extensively in different circuits. a zero-current zero-voltage transition PWM boost converter was put forward, which was formed by the application of zero transition circuit into boost converter and whose main switch can

achieve zero-current turn-on under traditional modulation strategy. The change to the modulation strategy can make main switch achieve zero-voltage zero-current turn-on and auxiliary switch achieve zero-voltage zero-current turn-off in advance.
