Stabilizer Step up 110V AC to 230V AC 500VA
It can Stabilize Mains voltage to around +/- 10% .
It can be used for both 110V AC or 220V AC inputs
with modifications. The Output is 220V AC. There
is an overload, under voltage and over voltage
Stabilty and Supply Regulation
U2A and U2B are two comparators which controls
relays K2 and K3 Respectively. One Boosts the
voltage (Step-up) when mains supply is low. The
other Bucks the voltage (Step-down) when mains
voltage goes beyond a limit.
Power Inverter and DC to AC
U2C and U2D work like a window comparator to trip
the unit above and below certain preset limits.
This circuit is clubbed with a Mains control relay
K1 which can be Turned ON-OFF with two
This circuit is a design i did, not tested by me
as yet.With some tweaks and modifications it might
