摘　　要：分析了滞环控制工作原理,详细推导了开关频率计算公式,得到开关频率与指令信号变化率关系,在此基础上设计了分段滞环控制电路。实验结果表明,此电路能够基本保证开关频率固定。The principle of hysteresis control is analyzed. The switching frequency formula is derived in detail. The relationship of switching frequency with the rate of change of reference signal is deduced. The sectional hysteresis control circuit is designed based on the referred theory. The experimental results show that this circuit can be used to basical y guarantee the stability of the switching frequency.
