Subject: SSTC half bridge

 Hello,

 I am planning on building a SSTC, driven by a half bridge of POWERMOSFETs.
Searching the archives and the web, I found two topologies:

 a.                    +340 V

                          |
                 upper FET
                          |
                         *------ primary coil--------------
                          |                                          |
                 lower FET                                   = dc blocking
capacitor
                          |                                          |
                    GND                                    GND


 b.                    +340 V
                          |
                         *------------------------------------
                          |                                          |
                 upper FET                                  =  dc blocking
capacitor
                          |                                          |
                         *------ primary coil-------------*
                          |                                          |
                 lower FET                                   = dc blocking
capacitor
                          |                                          |
                     GND                                    GND

 What are the pros and cons for these circuits? Could somebody please
enlighten me?

 Regards,

 Herwig
