SPICE simulation of a Combo Wave Generator.

 

Coupling and Decoupling networks.

Each coupling/decoupling network (CDN) consists of a decoupling network and a coupling element as shown below

For line-to-line coupling, the surge shall be coupled by an 18uF capacitor –Differential Mode:

GPM – Surge Generator Validation.

Sahara3 6W board was used to validate the surge generator by measuring the voltage on C229 and comparing with simulation results at 1KV surge and 3KV surge in standby mode, Standby power about 1W
