Notes:
(1) The V CE detection diode should have a blocking voltage rating equal to or greater than the V CES of the IGBT
(2) DZ1 is necessary to protect Pin 30 of the driver from voltage surges during the recovery of D1.
(3) Power supply input and output decoupling capacitors should be connected as close as possible to the pins of the gate driver.
(4) DC-to-DC converter output decoupling capacitors must be sized to have appropriate ESR and ripple current
