Abstract

PURPOSE:To enable highly efficient charging through a simple and small device, by setting the driving frequency of a switching element at a level higher than a predetermined level and exciting a recharging coil. CONSTITUTION:A.C. current having constant frequency flows through an oscillating section 1 and switching elements 2-5 to a recharging coil section 6. Flux produced by the current flows through a magnetic circuit consisting of a coil yoke in the recharging coil section 6 and core of coil in an electronic clock arranged on a recharger. Consequently, voltage is induced in a secondary coil and a secondary cell is recharged. Driving frequency for the switching elements 2-5 is set higher than 200Hz.
