INRUSH CURRENT CONTROL DURING STARTING OF RESONANT CONVERTERS |
摘要 |
A converter with soft start includes a transformer; first and second switches connected to the transformer to supply power to the transformer; a controller connected to the first and second transistors and arranged to, during startup of the converter, switch the first switch with a variable duty cycle and switch the second switch with either a fixed duty cycle or a variable duty cycle with pulses larger than pulses of the variable duty cycle of the first switch; and a bleed device arranged to set initial conditions of the converter before startup of the converter by discharging a capacitor in the converter before startup. |
