Title: Chopper type power supply
Inventor: MORITA KOICHI
IPC: H02M3/155
Filed: 1990-11-27
Abstract: PURPOSE:To suppress surge voltage and noise component by a constitution wherein energy stored in a second reactor is discharged upon turn OFF of a chopper switch and a current is fed to a circuit comprising a DC power supply, a first reactor, a capacitor, a switching element and a load thereby a surge voltage is absorbed. CONSTITUTION:Since a capacitor 28 is charged with a voltage higher than the power supply voltage during OFF interval of a FET 5a, discharging current I3 of the capacitor 28 flows through a closed circuit of the capacitor 28, the FET 5a, a load 6, a smoothing capacitor 11 and a second reactor 12 during an ON interval t1-t2 thus feeding power to the load 6 and storing energy in the second reactor 12. A surge voltage is produced during an OFF interval t2-t3. But the current I3 flows through a closed circuit of a first reactor 4, the capacitor 28, a diode 14, the load 6, the smoothing capacitor 11 and a power supply 1 and the capacitor 28 absorbs the surge voltage.

Abstract: PURPOSE:To attain the operation with a single power supply covering a small operation range by providing a switch switched synchronously with an intermittent signal and a circuit providing an offset, giving the offset at an ineffective signal and passing a signal at an effective signal so as to eliminate the DC offset. CONSTITUTION:A pushbutton signal generating circuit 11 outputs an intermittent signal with a DC offset (e.g. 2V) superimposed thereon. In this case, a switch 14 is controlled by an MPU 12 and thrown to the contact 15 at the output of an effective signal, and the effective signal passes through a capacitor 17, and the switch 14 is thrown to the contact 16 at an output of an ineffective signal and a 2V offset is given by bias resistors 20, 21. Thus, a mean voltage at a point D is 2V independently of the position of the switch 14. Since a DC offset is eliminated, the signal amplitude is decreased and the circuit operation is attained with a single power supply with a small operation range.
