ABSTRACT:
An electronic AC voltage stabilizer using a class B amplifier output stage which is fed by a full-wave rectified sinewave voltage. The input voltage to (the phase inverter of) the class B amplifier output stage is kept in phase with the aforesaid sinewave voltage, which causes the power losses in the output stage to be very low. As compared to other electronic AC stabilizers, the apparatus according to the invention offers high efficiency and simplicity. The AC stabilizer can easily be converted into a true uninterruptible power supply (UPS) by adding a battery which through a battery interface circuit connects the battery voltage, after it has been appropriately converted into a full wave rectified sinewave voltage, to the push pull amplifier output stage when a power network fails.
