ZVS CIRCUIT COMPATIBILITY WITH THE POWER SUPPLY RECTIFIER BRIDGE
In some cases, the operation of the ZVS circuit may require a small capacitor C
ZV
on the pin SYN in
addition to the resistor R
ZV
. The diodes of the full wave rectifier bridge may have a low speed and may
switch off with recovery charges that create spikes on the pin SYN as shown on the waveforms below. With
a10k
- 22nF RC circuit, the ZVS circuit becomes immune to such spikes.

OPEN DOOR SIGNAL IMMUNITY
The door-closed signal is achieved by a high side switch connected between the VCC polarity and the DS
pin.Whenthedoorswitchisoffandthemagnetronrelaycoilisnotsuppliedanymore,thelowstatesignalis
secured by the internal pull-down resistor of DS pin (50k
).
In noisy environment with radiated interferences, the off state of the DS signal (open door) can be
reinforced by adding a resistor from DS pin to the ground COM. Its resistance can be chosen from 50 k
to
22 k
.
