3 adopt the angle of flow of the single bidirectional triode thyristor of control, and the voltage drop when utilizing not conducting on the controllable silicon is logical

Cross the method for electric capacity, its two-way admittance angle to the electrochemical capacitor charging of control module self DC power supply

Be to be produced by time-delay the zero point according to AC power by control module, its two-way admittance angle is a phase

With, and bigger, the product infrared induction that sees Guangzhou strange bt appliance company is automatically opened

Close, model is E2751/2-GA.

Heat dissipation problem when 1st, 2 kinds of methods all exist diode or triode self and flow through big electric current,

The silicon controlled angle of flow is big in 3 kinds of methods, makes switch reduce the efficiency of transmission of electric energy.

The utility model electronic switch module produces at above-mentioned two kinds of problems design, has both reduced

Heater element has improved electric energy conducting efficient again, and a small-power can also be provided for external control module

DC power supply, the utility model electronic switch module can with according to sound, visible light, infrared ray, people

The different control module that various signals such as body pyroelectricity, radio frequency are made is used the utility model

Electronic switch module is to be in conducting or disconnection according to the control signal that external control module is exported

State.Under the state of switch conduction, use electrochemical capacitor that switch self power supply is charged,

On the The Trigger of Bidirectional Triode Thyristor mode, adopt two-way asymmetric mode, can when having reduced not conducting

Voltage drop and reduced the triggering and conducting angle on the control silicon has improved the electric energy transmitting efficient of switch.

See accompanying drawing 1, the connection features of each components and parts is in the utility model electronic switch module: at electronics

Be connected to capacitor C 1, resistance R 1, R2, R3, voltage-stabiliser tube between switch module lead-out terminal J1 and the J2

Be elaborated below in conjunction with accompanying drawing 1 and 2 pairs of this novel practical electronic switch module of accompanying drawing.

Load LOAD and C1 in the accompanying drawing 1, R2, D1 for switch not the E1 during conducting provide half-wave to fill

The electricity loop, E1 provides power supply for control module and T1, and the magnitude of voltage on the E1 is that the voltage stabilizing value of Z1 deducts

The forward conduction magnitude of voltage of D1, R3 is used for the trigger current of restricted T 1, the output of external control module

T1 conducting when control signal is low level, load LOAD and T1, Z1, Z2 provide for T2 at this moment

The conducting trigger port, T1 and E2, R1, D2, D1 and load LOAD form unidirectional to E1 simultaneously

Quick charge passage, R1 be simultaneously also for E2 provides discharge channel, the voltage stabilizing value of Z1, Z2 utilization itself

Provide two kinds of different trigger voltage value with forward conduction voltage drop for T2, see J1 terminal phase in the accompanying drawing 2

Voltage V for the J2 terminal _J1-J2Signature waveform.Hand at 50Hz, 220V under the state of T1 conducting

Following four kinds of states are arranged in the one-period 20mS of stream power supply:

1 A point is between the B point, and T2 is conducting not, and switch is in half conducting state, AC power by E2,

R1, D2, T1, D1 and load LOAD charge to E1, the voltage VB width of cloth that B is ordered

The degree value is the conduction voltage drop that the voltage stabilizing value sum of Z1, Z2 adds T1, and its value can be less than 25V.

2 B point is between the C point, the T2 conducting, and the complete conducting of switch, the voltage on the switch is reduced on the T2
