Abstract

The present invention provides a kind of voltage drop-type DC-DC converter that controls the duty of a switching element by using a low-cost, space- saving and simple circuit without using a complicated oscillation circuit. In the voltage drop-type DC-DC converter of this invention, a switching element Q1 that supplies electric power to a load from a DC power supply is switched by a control circuit 3, which is provided with a differential amplifier 4. In the differential amplifier 4, a load voltage is inputted to the negative input terminal via a CR delay circuit 5, and the output of the differential amplifier 4 is fed back to the positive input terminal by a pull-up capacitor C1. The switching element Q1 in a hysteresis state is changed over so as to be turned on and off by the CR delay circuit 5 and by the pull-up capacitor C1.

Description of invention (2) This paper An important object of the invention is to provide a voltage drop type DC-DC converter that does not use an oscillator circuit and controls the operating ratio of the switching element with a very simple, low-cost and space-saving circuit.炤 定 頴 頴 Xifeng Duan® The reduced DC-DC converter of the present invention includes a switching element Q1 that supplies power from a DC power source to a load, and a control circuit 3 that controls the ON-OFF operation of the switching element Q1 to control The circuit 3 is provided with an operational amplifier 4 0. The lotus amplifier 4 pseudo-intermediates the CR delay circuit 5 and inputs a load voltage to the negative input terminal, while the reference voltage is input to the positive input terminal. The capacitor C1 is also pushed up to the lotus root amplifier 4 Output. The CR delay circuit 5 delays the fluctuation of the load voltage and inputs it to the negative input terminal of the lotus amplifier 4. The push-up capacitor C1 inputs the output voltage when the operational amplifier 4 is in a “high state” to the positive input terminal, and then temporarily increases the reference voltage and gradually decreases. When the switching element Q1 is OFF, the falling load voltage pseudo-intermediate CR delay circuit 5 gradually decreases the voltage of the negative input terminal, and when the voltage of the negative input terminal is lower than the voltage of the positive input terminal, the lotus amplifier 4 The output 卽 is set to a "high state" and the switching element Q1 is switched to ON. And at this time, the push-up capacitor C1 temporarily raises the reference voltage with the “high state” voltage to keep the output of the lotus amplifier 4 in the “high state”. After that, when the push-up capacitor C1 is charged and the reference voltage gradually drops to a value lower than the load voltage, the output of the operational amplifier 4 becomes a "low state" and the switching element Q is switched to OFF. That is, the push-up capacitor C1 is to feedback the output of the lotus computing amplifier 4 to the positive input A7 (please read "-side notes before filling out this page) This paper size applies the Chinese National Standard (CNS) M specifications ( 210X297) 2 3 9448 Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Waves ^ 3 71 44 A7 V.

In the DC-DC converter, when the switching element Q1 is turned on, the rise of the electric power S of the negative input terminal is accelerated by the power supply voltage. The higher the power supply voltage, the faster the voltage at the negative input terminal rises. Therefore, when the power supply E is high, the high state time of the negative input terminal is shorter than that of the positive input terminal, and the switching element Q 1 is switched to 0 F F in a short time. When the DC source voltage is high, the ON time of the switching element Q1 is shortened, and when the DC power source voltage is low, the 0H time of the switching element Q1 is lengthened. Therefore, under the fluctuation of the DC power source voltage, the load power can be reduced. change.

Description of the Invention (6) Switch the ON-OFF action of the switching element Q1. (1) When the power switch 6 is ON, the switching element Q1 is in the OFF state, so the load The voltage is 0V. (2) At this time, because the positive input terminal of the lotus computing amplifier 4 is supplied with the reference voltage, the voltage of the positive input terminal of the lotus computing amplifier 4 is higher than the negative input terminal and the output is high. State M voltage. (3) The "high state" output of the lotus computing amplifier 4 switches the driving transistor Q 2 to ON. (4) When the driving transistor Q 2 is at 0K, the base current is supplied for exchange Element Q 1, and the switching element Q 1 is switched to ON. (5) In the ON state The switching element Q1 is connected to the electric heater 2 of the battery 1 and supplies power to the electric heater 2. (6) The voltage applied to both ends of the load is mediated by the CR delay circuit 5 and input to the negative input terminal of the lotus amplifier 4. CR delay Circuit 5: Even if the load voltage is formed equal to the battery voltage, it will delay the voltage rise of the negative input terminal. Therefore, if the battery voltage is supplied to the battery voltage, the voltage of the negative wheel input terminal does not rise immediately, but gradually Going high (7) On the other hand, when the output of the operational amplifier 4 is in a "high state", the "high state" voltage system pushes up the capacitor C1 and then increases the output of the lotus amplifier 4. The capacitor is pushed up The voltage of the positive input terminal C1 decreases with reference to the reference voltage. U) The voltage of the positive input terminal gradually decreases as the charging status of the capacitor C1 is pushed up, and the voltage of the negative input terminal goes to CR.
