3.2.1 Waveforms

After completing the recommended test setup, verify that the following channels are displayed in the waveforms in Figure 3-2

  • CH 1 = HV+
  • CH 2 = S2
  • CH 3 = VDD/EN
TPSI2240Q1EVM Voltage Sense Output (S2) Test Point at HV = 800V (EN = 5V)Figure 3-2 Voltage Sense Output (S2) Test Point at HV = 800V (EN = 5V)

Figure 3-3 shows two test points using the following channels settings.

  • CH 1 = VHipot (HV+)
  • CH 2 = S1-S2
TPSI2240Q1EVM Secondary Sense (S1) and Voltage Sense (S2) Test Points at HV = 4300VFigure 3-3 Secondary Sense (S1) and Voltage Sense (S2) Test Points at HV = 4300V
