FORWARD TYPE BOOST DC-DC CONVERTER FOR STABLE PEAK INJECTION OF ELECTRIC UNIT INJECTOR

摘要

A forward type boost DC-DC converter for stable peak injection of an electric unit injector is provided to reduce heat in a high speed switching process and to obtain the maximum fast response time of a peak through the stable high speed switching by connecting two switching FETs in parallel. A boost DC-DC converter has two parallel FETs and a filter. Two parallel FETs are designed to perform a high speed switching for boosting an input voltage or 24V to 110V. The filter blocks an in-rush current and removes an overshoot when applying an initial power, and minimizes a ripple voltage generated when maintaining stable 110V power.
