What are the advantages of vehicle module power supply?(2)

(1) It has a particularly wide range of uses, not only aerospace, post and telecommunications, but also metallurgy, mining, automatic control, etc., whether it is social production or daily life, it can be well used;

Power active filter is a new type of power electronic device that can dynamically suppress harmonics. It can overcome the shortcomings of traditional LC filters and is a promising harmonic suppression method. The filter consists of a bridge switching power converter and a specific control circuit. The difference from the traditional switching power supply is: (1) not only feedback the output voltage, but also feedback the average input current; (2) the current loop reference signal is the product of the voltage loop error signal and the full-wave rectified voltage sampling signal.

(2) vehicle module Marine boost/buck voltage power supply  The quality is relatively excellent, the quality is relatively stable and reliable, and it can be produced automatically;

(3) The technology is relatively simple, and it is easy to meet the relevant requirements;

(4) vehicle module Marine boost/buck voltage power supplyThe development cycle is relatively short, there are many choices in input and output, and the changes are quite flexible;

(5) When the design of the product needs to be changed, it can be simply converted or connected in parallel;

Remote control switch circuit
The remote control switch operation of the module power supply is carried out through the REM terminal. There are two general control methods:
(1) REM is connected to -VIN (reference ground), the remote control is turned off, and VREF<0.4V is required. REM is suspended or connected to +VIN, the module works, and VREM>1V is required.
(2) REM is connected to VIN, the remote control is turned off, and VREM<0.4V is required. REM is connected to +VIN, the module works, VREM>1V is required. REM is suspended, and the remote control is turned off, that is, the so-called "suspended shutdown" (-R).
If the control is to be isolated from the input, an optocoupler can be used to pass the control signal

(6) vehicle module Marine boost/buck voltage power supply The design is relatively simple, without too many parts, just a power module and a few discrete components;

 In many fields, switching Marine boost/buck voltage power supply modules play a role that cannot be ignored and are very important.
