Abstract:

A DC/DC voltage booster circuit is essential to design for the high-pressure (H.P.) injector driving circuit since the power supply voltages for various H.P. injectors are DC 60~90 V rather than DC 12~14V battery voltages. The DC 12~14V battery voltages have to be boosted up to the stable DC 60~90 V voltages supply for being able to drive various H.P. injectors. The new H.P. injector driving circuit consists of a voltage booster circuit and an originally designed three-stage power MOSFETs injector driving circuit to control the dc-link power supply voltage. The dynamic performance of a H.P. in

The conventional high power switch mode power supply consists of an AC/DC conversion with boost converter followed by a DC/DC converter to produce dc voltage.
