CIRCUIT
SUMMARY OF THE INVENTION
In the application of batteries, the batteries are usually series and parallel combined to control the output voltage, whereby the voltage stages are series and parallel combined to drive the load, and the control is by series combining the linear components between the output voltage and the load or by installing the. cut-off switches, thereof the applicant has disclosed an innovative design of highly efficient multiple voltage stages output circuit in the previous applied British Patent Application No.
9205867.6 in which the solid state power components are incorporated with the voltage stages switching to provide the PWM chopped low wrinkle wave voltage output; whereof the solid state switching component for PWM control is series combined between the switching contacts which are constituted by the batteries and diodes to allow for multiple voltage switching, thereby to generate a linear continuously modulated PWM output with the low voltage as the bottom value and the high voltage of neighboring section as the peak value, and the currentlimiting ,constant current, or constant voltage output modulation functions are provided through feedback, and the applicant has done successive research in the claim to further develop that the combined terminal between the solid state stitching component and the battery is relocated from the battery switching terminal to the batteries parallel combined output terminal, therefore this progressive advantage is characterized in reducing the power loss of voltage drop and the component heat loss for the solid state switching component at its maximum output.
BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 is an embodying example of the invention illustrating that two batteries are employed for continuously modulated control output.
DETAILED DESCRIPTION OF THE INVENTION
In figure 6 of the applicant's British Patent
Application No. 9205867.6 (refer to enclosure 1), solid state switches are employed for the common divisor combined multiple voltage stages control circuit, and the solid state switching component SSU100 is installed between the battery output and the load to provide PWM output control ranging from zero voltage to the neighboring staged series and paralleled combined voltage, wherein full conduction is achieved at each voltage stage and voltage drop is presented between the two terminals, whereby to generate a greater power loss.
To improve the above disadvantage, the diodes series
combined with each battery in the original design is
replaced by the individual solid state switching
component to substitute for all the solid state
switching components between the batteries and the
ioad to allow for the PPM control ranging from zero
voltage to neighboring series anc parallel combined
voltage stages, thereof the system operation of the
cordon divisor combined multiple voltage stages
control circuit presents the following functions and
characteristics:: (1)Based on the common divisor number of batteries to
install corresponding switches, the most or several
of the multiple voltage stages output status can be
selected;
(2)In low voltage output, all solid state switching
components series combined with the batteries are
parallel combined, whereby the output current is
parallel distributed to reduce the current flowing
through each solid state switching component so as to
lower the forward bias voltage drop and heat loss of
each switching component
(3)In maximum output, as the solid state switching
components series combined between the whole
batteries and load for PWM control from zero voltage
to neighboring voltage stages are not required to
install, the cost can be lowered and power loss and
heat loss can be reduced.
Figure 1 is an embodying example of the common divisor combined multiple voltage stages control circuit illustrating that two batteries are employed for continuously modulated control output, wherein it is mainly comprised of the following:
The batteries U1, U2: They can be the rechargeable
secondary battery or primary battery, whereof the
positive terminal of the battery U1 is connected to the
positive terminal of the load, and the negative
terminal of the battery U1 is connected to the positive
terminal of the battery U2 in the direction of polarity
through the solid state switch SSU101, while the
negative terminal of the battery U2 is connected to the
negative terminal of the load;
A solid state switch SSU102:It is series combined
between the positive terminal of the battery U1 and the
positive terminal of the battery U2 following the
direction of polarity;

negative terminal of the battery U1 following the
direction of polarity;
If the solid state switches SSU102 and SSU103 have the
reverse voltage resistant unidirectional conduction
characteristic f (such as a SCR or IGBT with internal
series combined diode or other solid state power
transistor), then they can be used directly; therein if
they do not have the reverse voltage resistant
characteristic, the diodes CR102 and CR103 can be
separately series combined to protect the switches from
damaging by the reverse voltage;
A input control device IP100: It is constituted by
solid state or electromechanical components to accept
the manual operation or the digital or analog
electrical signal for transferring to the central
control unit CCU100; A current detector device CT100: It is series combined
at the output terminal to detect the output current
value and feedback to central control unit CCU100; A central control unit CCU100:: It is constituted by
solid state or electromechanical components, whereof it
is installed with internal setting value and relevant
software to correspondingly control the solid state
switches based on the feedback from the input control
device IP100, or the current detector device CT100 or
the voltage detector device VT100; A voltage detector device VT100: It is parallel
combined at the output terminals for detecting the
output voltage value and feedback to central control
unit CCU100.
The output voltage control process is shown in Table 1, wherein if EB represents the voltage unit of a battery, then the voltage output status is from output status S1-+ output status S2-+ output status S3, respectively from zero to the maximum output, wherein the work status of the solid state switches for each output status is delineated as following:
Output status S1: At this time the solid state switches
SSU101, SSU102, SSU103 are at open circuit cut-off status, and the output voltage is zero;
Output status S2: At this time the solid state switch
SSU101 is at open circuit cut-off status, and SSU102, SSU103 are at closed circuit conducting status, while the battery is providing parallel combined output, wherein the output voltage is Ebxl value (Disregarding the solid state switch voltage drop
Output status S3: At this time the solid state switch
SSU101 is at closed circuit conducting status, and SSU102, SSU103 can be either at open circuit cut-off status or at closed circuit conducting status, while the batteries are providing series combined output, wherein the output voltage is a high voltage value of Ebx2 (Disregarding the solid state switch voltage drop ).
Through the continuous operation exchange of the output status S1, S2 and S3 as well as through changing the time ratio of operation exchange, an improved PWM continuous output from zero to the maximum value with the previous stage voltage as the bottom value can be constituted, wherein the continuous status includes the following: (1)Output cut-off: It appears in S1 output status,
wherein the solid state switches SSU101, SSU102,
SSU103 are all at open circuit cut-off status;
(2)Cut-off to EBxl output:At this time the S1 output
status and the S2 output status are operated in turns
to provide voltage output from zero to the parallel
combined Ebxl output voltage status of each battery
(Disregarding the solid state switch voltage drop ),
wherein the loading current is PWM chopped wave
controlled through the parallel distributed current
of the two solid state switches SSU102 and SSU103;
(3)EBxl output: At this time it appears in S2 output
status (disregarding the solid state switch voltage
drop ); (4)EBxl to EBx2 output:The output status S2 and 53
output status are operated in turns, and it is
through the switching operation of interchanging
conductions between the solid state switching
components SSU102 and SSU103 and the solid state
switching component SSU101 to provide from the
parallel combined EBxl output status of each battery
to the series combined Ebx2 voltage stages status of
the batteries to achieve the PWM continuous output
voltage modulation with the parallel combined voltage
stage as the low voltage value and the series
combined voltage stage as the high voltage value
(disregarding the solid state switch voltage drop );
(5)EBx2 output:It appears in the continuos output of
the S3 output status, wherein the solid state switch
SSU101 is at closed circuit conducting status while
the output voltage is the highest value of EBX2
(disregarding the solid state switch voltage drop).
The afore mentioned batteries U1, U2 can be constituted into a voltage unit by randomly selecting any voltage values of batteries with same voltages, whereof in the embodying example, the voltage unit is constituted by the two batteries U1, U2, whereof in the practical application, the voltage unit can be enlarged from the afore mentioned two batteries to more than two batteries based on the same principle, thereof the batteries and switching components shall be based on the adopted number of voltage constituted by batteries and matched with the solid state switching component installed between the employed voltage units at the common divisor series and parallel output status of the system operation; thereof if EB represents the voltage of each battery, then for the instance of 3 voltage units, the two voltage stages output of lxEB and 3xEB can be obtained; for 4 voltage units, multiple voltage stages output of 1xEB, 2xEB, 4xEB can be obtained; for 24 voltage units, the multiple voltage stages output of 1xEB, 2xEB, 3xEB, 4xEB, 6xEB, 8xEB, 12xEB, 24xEB can be obtained; for 36 voltage units, the multiple voltage stages output of lxEB, 2xEB, 3xEB, 4xEB, 6xEB, 9xEB, 12xEB, 18xEB, 36xEB can be obtained, i. e. the number of voltage stages output can be selected according to the multipliers of the common divisor number of the number of the battery voltage units, so the other number of voltage units can deducted as above which is not repeated here; therefore for a common divisor combined multiple voltage stages control circuit with two or more than two voltage stages output, all or part of the voltage stages can be selected to constitute a multiple voltage output.
As is summarized from the above description, the design further provides an innovative design of low loss control circuit to generate common divisor combined multiple voltage stages output, and is combined with wave chopping control solid state switching component to obtain the multiple voltage switching and the PWM chopped low wrinkle wave voltage stages output; therefore the design is innovative with clear defined functions, and your legal approval of the claim is greatly appreciated.
