ABSTRACT:
A multiplier using Hall element comprises a Hall element with a pair of control current input terminals and a pair of Hall output terminals, an electromagnet for converting load current into magnetic field and for applying the magnetic field to the Hall element, a transformer for converting load voltage into control current, and a constant current circuit for making the secondary current of the transformer constant and then feeding it to said control current input terminals. The Hall element produces across the pair of Hall output terminals Hall output voltage corresponding to the product of the load current and the load voltage.
