The regular type BOOST SMPS uses switching that connects to ground directly, which does not allow main current to go through 1.5MH coil and load. I need the back EMF of coil to assist the main flow through current to a load , so as main current pulse and low volts is aided by the higher EMF pulse directly after. An inverse parallel diode to A coil just wastes the inherent balance of energy. (I need 2 pulses to load) Do you know if- after the polarity of coil automaticlly switches around, during off time of half wave DC input, does the higher volts also automatically follow the main pulse in same direction? A neon bulb in circuit may show as indicator if parallel to the resistor load in series. (greater than 90 volts) Is this true? This was from a circuit in 2008 Georgia that added about 100 volts to 12volts pulses- no diagram available.
