Abstract
Loads connected in parallel with the supply (the supply being normally A.C) are normally controlled using series rheostats etc. resulting in loss of energy. The loads normally are light and fan loads having power ratings ≤100W. For controlling power fed to these loads the supply can be of mixed type (discussed later to be both A.C and D.C). D.C supply which can be easily obtained using rectifiers can be used to drive fans. The A.C input to the rectifier can be passed through a suitable load which was previously connected in parallel with the supply. Generally lighting and charging loads are highly suitable for this purpose. Another perspective of this circuit is the possibility of synthesizing hydrogen (an alternate fuel) and oxygen. When properly designed light, motor and charging load may be simultaneously applied. Thus the power previously being wasted in the power controlling device is now being used up by separate devices increasing efficiency.
