Embodiment
In Fig. 2,1 is electrical appliance, including household electrical appliance, illuminator, electric tool etc..K, K1 are respectively that electrical appliance is carried
Switch and backup bypass are opened.D1, E are respectively isolating diode and battery, and parameter is according to the load L of electrical appliance 1 specified work(
Rate determines that battery includes super capacitance cell, the various rechargeable batteries with charge-discharge protection circuit one.Q1, ZD1 are respectively
Controllable silicon and voltage-stabiliser tube diode.2 be bridge rectifier, can be common separation element, or high power module, ginseng
Several load L according to electrical appliance 1 rated power is determined.3 be bypass protection circuit, by controllable silicon Q1 and voltage-regulator diode ZD1
Composition, controllable silicon Q1 can be one-way SCR, or bidirectional triode thyristor, and the size of its power is also with bridge rectifier power
Quite, voltage-regulator diode ZD1 power is determined by controllable silicon Q1 parameters, and voltage-regulator diode ZD1 voltage stabilizing value parameter is according to electric power storage
Forward conduction voltage sum of the pond E maximum charging voltage and isolating diode in charging is determined.The friendship of bridge rectifier
Stream input (AC1, AC2) is connected in series in the optional position in city's electrical circuit of electrical appliance 1, including is connected in series in multiple electrical appliances 1
The optional position in the total loop of civil power, the DC output end (DC1, DC2) of bridge rectifier simultaneously couples bypass protection circuit
With the two ends after isolating diode D1 and battery E series connection.Backup bypass switch K1 is connected in the exchange of bridge rectifier
Input (AC1, AC2), as standby, is usually off-state.
Circuit theory is referring to Fig. 2, (the note when closing the electrical appliance of electrical appliance 1 from belt switch K：Backup bypass switch K1 breaks
When opening), now in two kinds of situation：
The first situation, in battery E power shortages, voltage-regulator diode ZD1 voltage stabilizing value is higher than battery E both end voltage
With isolating diode forward conduction voltage sum, voltage-regulator diode ZD1 cut-offs, controllable silicon Q1 is also switched off, and civil power passes through electrical appliance 1
Load L decompressions, and after the rectification of bridge rectifier 2, pulsating direct current is charged through isolating diode D1 to battery E to be turned on,
Now charging current is the electric current of the load L by electrical appliance 1, the normal work of electrical appliance 1.When battery E both end voltage
Slowly raise, when adding isolating diode forward conduction voltage sum and being higher than voltage-regulator diode ZD1 voltage stabilizing value, immediately enter the
Two kinds of situations, battery E stops charging.
Second of situation, when battery E fills with electricity, voltage-regulator diode ZD1 voltage stabilizing value is less than the two of battery E
Terminal voltage and isolating diode forward conduction voltage sum, voltage-regulator diode ZD1 conductings start controllable silicon Q1 conductings, and civil power leads to
The load L of electrical appliance 1 is crossed, and after the rectification of bridge rectifier 2, controllable silicon Q1 of the pulsating direct current through bypass protection circuit 3 is led
Logical, conducting electric current is the electric current of the load L by electrical appliance 1, protects overcharge of a battery, the normal work of electrical appliance 1.
Under above-mentioned both of these case, such as mains failure or electrical appliance open fault, now, such as charging based on electrical appliance
LED/light source and power-off inspection side device are had additional after circuit, you being reminded as power-cut emergency lighting and electrical appliance open fault should
With.
Power network peak times of power consumption voltage it is relatively low or be not intended to based on electrical appliance charging circuit work when can close it is standby
With by-pass switch K1, backup bypass switch K1 is disconnected when the power network low power consumption phase, voltage was higher can recover to be based on electricity consumption
The charging circuit work of device, also acts as the effect of protection electrical appliance.
(the note when disconnecting the electrical appliance of electrical appliance 1 from belt switch K：When backup bypass switch K1 disconnects) electrical appliance should be based on
Charging circuit be stopped naturally, now, had additional after such as charging circuit based on electrical appliance LED/light source and power-off inspection side dress
Put, you can illuminated or emergency lighting application as switch time delay is disconnected.
