Few errors in Bedini Pulse Charger US PAT 6677730
- The +12V power source should not go to the H11D3 LED. This is supplied via the pin 11.
- The SG3524N does not have sink capability. Hence, the LED cannot bleeds off. Suggest to use another controller or add a bleeding resistor (e.g. 500 ohm) at pin 11 and pin 14.
- Pin 9 and Pin 1 need to be connected to get the EA line crossing the saw tooth wave.
- The 2K ohm resistor is pulled to ground. It doesn't seem to work well by connecting as diagram. Comment??
- The cap voltage is always lower than input voltage. May be the Vgs turns off when it charges up. Vgs 2-4V.
- Patent suggest 2k ohm between gate and drain of IRF260.(the 2nd drain?)
