VRGLH is the maximum value and VRGLL is the minimum value of the coupling waveform during the period from
Point A in the above diagram until the rising edge of RG. In addition, VRGL is the average value of VRGLH and
VRGLL.
VRGL = (VRGLH + VRGLL)/2
Assuming VRGH is the minimum value during the interval twh, then:
VφRG = VRGH – VRGL
Negative overshoot level during the falling edge of RG is VRGLm.
