| 总结: | Capacitor can be used as an energy storage element to supply small power in
replacing a battery. The advantage of using capacitor is the charging time is much faster than charging a battery. But the disadvantage is that the capacitor voltage value is not constant to supply a load. From that, a dissertation project has been conducted to design a controller using boost converter to regulate the capacitor voltage output. The
boost converter used to control the voltage level. The boost converter circuit is constructed with power switch MOSFET. To generate pulse width modulation (PWM)
to the MOSFET, a PIC16F877 used to drive PWM at specific switching frequency. The
output voltage will step up from input voltage and use to operate the load. In this project, the complete circuit is designed using Matlab Simulink software with a specific value of parameter components. The design parameter is simulated and implemented
into hardware and tested to get the result. There are two experiment has been handled. The first is the measurement of voltage output capacitor when connecting with or without controller and second is the controller design is connected to a load. From the
experiment, the output voltage capacitor for circuit without boost converter has the
result proportionally to the voltage input and the effect of the load. The circuit with
boost converter is maintained at 24V for every voltage input and also connected to
various load. |
