Voltage control of bidirectional DC-DC converter with constant power source

—Bidirectional DC/DC converters are used in the interface of the battery bank and the high voltage direct current terminal of an inverter. The performance of the system depends on the control of voltage and current across the circuit. Voltage control in eliminates the need for changing the control loop when the power supply is changed to the alternating current source. The report explains the constant power supply voltage control. The diagram for the bidirectional dc/dc converters is analysed and the mathematical representations are given. The dynamic performance of the circuit is calculated to give the efficiency of the system in DC-link voltage control.

Driving Circuit

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. injector driven by the designed electrical driving circuit with the voltage booster are simulated and analyzed. The stability and electrical characteristics for the voltage booster under various injection pulse durations and engine speeds are investigated. The fuel injection quantities, supply voltages and injector driving currents of the H.P. injector fed by the new injector driving circuit is illustrated and analyzed in the paper. The experimental results show that this injector driving circuit with a newly designed voltage booster is capable of operating stably to drive the H.P. injector and obtain the accurate fuel injection quantities in the air-fuel ratio control of engines.
