The objective of the thesis is to present newly developed AC driver and protection circuits for light emitting diode. The LED modules for each upper and low arm are with pulse-width modulation control in every half fundamental cycle. The indication and protection circuits act whenever short circuit and open circuit of LED module occur. Moreover, the current path is switched off when there is a short circuit of LED module.

目前一般白光发光二极体的驱动器，皆是使用直流电源驱动，本文利用发光二极体本身单向导通的特性，将发光二极体串接成桥式整流器的方式，只需控制流经中间路径的电流周期，就可达到调整发光二极体亮度之目的，并且增加发光二极体故障时的保护指示电路。

Signal forming and different demodulation of GMSK baseband signal are mainly discussed in the dissertation. Gauss Filter, phase integral, SIN table, matched filter, calculate angle, bit-synchronization、output filter、A/D、D/A and etc of GMSK baseband signal are carefully studied through software emulation in SYSTEMVIEW environment. The modulation and demodulation of GMSK baseband signal are carried out by the way of using TMS320VC549 of TI to integrate software and hardware.

Finally it mathematically calculates the CRC at bit and byte level and deducts a 16-bit CRC. The calculation and deduction consolidate the CRC theory. Chapter three also introduces the modulation by two, CRC polynomial, reflection polynomial applied in noise environment and the relationship between reflection polynomial and general polynomial.

第三章首先阐述了循环冗余码与循环码的关系——循环冗余码是一种短循环码、循环冗余码具有所有循环码的很多性质；然后，简单介绍循环冗余码的编码、译码原理和实现；最后，从普通数学的角度，分别用按比特、按字节求解CRC，详细推导了校验码宽度为16的CRC的理论过程，进一步为循环冗余码的研究提供有力的理论基础。

However, this modulation mode would not prevent the injection of DC current into the grid.

在双极性脉宽调制方式下，全桥逆变器的共模电压恒定，不产生共模电流。
