The constant frequency hysteresis is adopted to keep switching frequency stable and improve the hysteretic control.
为了克服滞环控制的不足，串联侧采用恒频滞环来保持开关频率的稳定。

Based on some simplified assumptions the equation for thermal hysteresis is introduced and a formula is thereby derived for calculating the time constant.
按一定的简化假设，建立了百叶箱热滞方程，井导出了百叶箱热滞系数的计算公式。
