Description

Automatic mutual-controlling program-controlled switch

The utility model belongs to noncontacting switch class field.

Several advanced persons' non-contact switch circuit is consulted China Machine Press's in April, 1986 Beijing front page " electric semiconductor circuit theory " P516 page or leaf " Figure 11-144 " and " Figure 11-146 "; Science Press's in November, 1988 the third printing " electronic circuit encyclopedia " P623 page or leaf " triode ac switch zero voltage switch "; " radio " magazine fifth phase P29 in 1988 page or leaf " application of novel solid-state relay "; Publish second edition " novel bidirectional triode thyristor trigger " " electronics newspaper " on September 11st, 1988; " electronics newspaper bound volume in 1987 " P168 page or leaf " accumulator cell charging and discharging automatic control circuit ".Look into " Chongqing patent place " Chinese patent bulletin, be difficult and this switchtype patent.

More than several circuit and other non-contact switch circuit following shortcoming is arranged respectively: (1) fail safe and poor reliability, especially with exchange (220V) power supply the switch of DC channel arranged; (2) function difference or function singleness, the automatic transfer process that has far need relay to help; (3) range of application is narrow or electric energy transmitting efficient is lower, and the zero-voltage-switch as 1988 10 phase P6 of " CYBERSPACE " magazine page or leaf " controllable silicon zero voltage switching circuit and application " is introduced is unsuitable for big inductive load, and incandescent lamp loads can produce scintillation; " electronics newspaper " second edition on September 11st, 1 " novel bidirectional triode thyristor trigger " circuit, because current-limiting resistance R resistance is big (～220V, MOC3041 get R=330 Ω), certainly lead to phase shift and influence electric energy transmitting efficient, controlled plant power supply accommodation is diminished.

The purpose of this utility model is the function that will enlarge noncontacting switch and improve the performance that exchanges scope solid-state switch (K part).

Circuit structure and operation principle: ginseng accompanying drawing

Automatic control cross complaint grammed switch is made up of direct voltage E, alternating current solid-state K switch and signal controlling T three parts, and shown in figure one (a), internal circuit configuration is shown in figure three.Direct voltage E is by control voltage V ₁With operating voltage V ₂Form, it is characterized by V ₁By bidirectional thyristor B ₁Output load R _DGeneration, V ₁Or V ₂With B ₁No DC channel.

Be with ※ number resistance to adjust among the figure three, to infinitely great, open a way during for infinity from zero.

Figure one (b) expression is with the control voltage V of two automatic control cross complaint grammed switches ₁Deliver to the other side's K respectively ₈Input point forms recriminating circuit, i.e. during one of them switch work, another switch just is closed, no V ₁Voltage output; Work with regard to operate as normal.

The implication of this switch automatic control is: a machine has assembled behind this switch according to functional requirement, can Auto Power On and shutdown.

The program control implication of this switch is: (1) microcomputer or the programme-controlled direct control switch of signal of telecommunication energy do not need function conversion and power amplifier intermediate equipment; (2) after many machines are installed this switch respectively, according to function and parameter be provided with different, can finish the work of certain program; (3) processes by the different situations electricity consumption, available switch finished, and as with this switch control charger, can charge to battery, and overvoltage or under-voltage stopping automatically being charged.

Compare with existing noncontacting switch, following advantage is arranged: (1) has enlarged the function of existing noncontacting switch; (2) improved the trigger sensitivity of alternating current solid-state switch, the actual measurement trigger current can be BG less than 3/ β milliampere β ₂Current gain; (3) zero passage is effective, and load capacity is strong, energy conversion efficiency height, input～220V.Output can reach～more than the 217V, and big inductive load also adapted to, to light flicker free phenomenon; (4) reliability height, leakage current was little when circuit turn-offed, and promptly output voltage can drop to " OV ".

Voltage stabilizing didoe B ₄To B ₅Protect, if B ₅Back-pressure height and performance good, also can cancel B ₄, trigger sensitivity is also better like this, perhaps adds B in debug process ₄, typing is cancelled B in producing again ₄
