Abstract

PURPOSE: To enable to obtain the switching power supply small in size, light in weight and efficient in the change of output power, by making most use of the switching element and the capability of transformer, in the power supply for electronic range.
CONSTITUTION: The voltage of the AC power supply 1 is rectified 17 and smoothed 20, allowing on and off in high speed of around 10 and its fraction of kHz by the turn-off thyristor GTO13 and the on-off current is fed to the load 11 via the transformer 4, switching transistor 7. In this case, since the circuit has inductance L10 such as reactor of wiring and stray capacitance C12, the current detection circuit 14 by a shunt is provided, and the comparison amplifier 15 makes decision so that the thyristor 13 is off at the current phase smaller than the average value of the circuit current, allowing to control the thyristor 13 with the driving pulse circuit 16. Thus, the switching element 7 and the capability of the transformer 4 can be optimized, allowing to obtain the switching power supply small in size, light in weight and efficient in the change of output power.
