IPC: H02M7/48
Filed: 1991-04-05
Abstract: PURPOSE:To obtain an AC-AC converter having high charging efficiency by providing a coil in charging circuit thereby chopping a switching element at high frequency. CONSTITUTION:A switching transistor(Tr) 31 is turned ON/OFF at a frequency in the range of several kHz-several tens kHz. A Tr 32 and resistors 33, 34 constitute a current limiting circuit which turns the Tr 31 OFF when a current higher than a predetermined level flows. A transformer 35 is excited intermittently through a Tr 37 and controls the Tr 31. The Tr 37 is controlled through an AND gate 38 by means of an output signal from a detecting amplifier 39 which receives a clock signal of several kHz-several tens kHz, the value of an output VXO, and deformation or distortion caused by the humidity, liquid temperature or gas pressure of a battery 42 at its detecting terminal 43 to produce an error signal. When the Tr 31 is turned ON, a coil 41 stores electromagnetic energy while charging the battery 42. When the Tr 31 is turned OFF, the loop is closed through a diode 42 to charge the battery 42 with thus stored energy. According to the invention, a charger having high charging efficiency can be obtained.
