Quadrature Phase Shift Keying is a form of Phase Shift Keying in which two bits are modulated at once, selecting one of four possible carrier phase shifts in 0, 90, 180, or 270 degrees

说明：  Description : This package includes a configurable Simulink model for three different types of DC-DC converters (Buck, Boost and Buck-Boost converters) with a PWM PI controller. The example provided shows a case to boost voltage 5 volts to 25 volts. It can be used to learn DC-DC converters and their control. The model itself also provides an example how to mask a subsystem in Simulink. A HTML and a pdf files are provided to explain the principles of the unform Simulink model for three different types of DC-DC converters. The model does not require other Simulink blocks, such as SimPowerSystems.
