The advantages of linear DC regulator are high stability, small ripple, high reliability, and easy to make a multi-output connected adjustable power supply. The disadvantages are large size, bulkiness, and relatively low power.
There are many kinds of this kind of regulated power supply, which can be divided into stabilized power supply, stabilized current power supply and stabilized current (double stable) power supply that integrates voltage stabilization and current stabilization. From the point of view of output value, it can be divided into fixed output power supply, band switch adjustment type and potentiometer continuous adjustable type, and from the output indication, it can be divided into pointer indication type and digital display type.
The switching regulator is a direct rectification to obtain a high-voltage direct current, and the output voltage is adjusted by a high-frequency oscillator controlling the time share of the switch switch on and off.
Switching power supply circuit is divided into series type and parallel type, the advantage of switching type regulated power supply is high power, because the transistor itself consumes very little power under the switching condition, can reach 70-80% or even higher power, and does not use a step-down transformer, its output transformer is operated by high frequency, and its volume is much less than 50 Hz power frequency transformer. Therefore, the circuit of the switching power supply is small and lightweight. Switching regulators are capable of operating at a wide range of voltages.
02. The essential difference between linear regulators and switching regulators
The switching voltage regulator is a different kind of regulated power supply from the linear voltage regulator, and its circuit types mainly include single-ended flyback, single-ended forward, half-bridge, push-pull and full-bridge.
The basic difference between it and linear power supply is that the transformer in the circuit does not work at the power frequency, but at tens of kilohertz to several megahertz. The power tube is not operating in the linear area, but in the full and cut-off area, that is, the operation is in the switching condition; This is where the switch-type DC regulated power supply comes from.
Everyday protection of linear and switching regulators
Whether it is a linear regulator or a switching regulator, their daily protection must start from the following aspects:
1. Always observe whether the cooling fan and transmission mechanism of the voltage regulator are running normally, check whether the input voltage and load exceed the additional scale, and deal with the abnormalities in time.
2. Protect the regulator once a month
1) Carefully clean all parts, especially the carbon brush, and contact the exposed part of the coil to remove dirt.
2) Check whether the internal components and wires of the voltage regulator are loose, and deal with them in time if there is a poor connection or poor contact.
3) Replace worn or damaged carbon brushes in time, and repair or replace faulty or damaged components in time.
