Pulse output period T1, T2, T3, T4 shown in Fig. 3 are equivalent to the pulse output period t2 shown in Fig. 2 and disconnection
Period t3 is added the period obtaining, and is based on processing conditions and determines, is processing period t4, T1=T2=T3=T4.Pulse
Output period T1, T2, T3, T4 are one group, will not only carry out certain one.That is, when entering the processing of horizontal pulse output period T1, also
Enter the processing of horizontal pulse output period T2, when entering the processing of horizontal pulse output period T2, also enter horizontal pulse output period T3's
Processing, when entering the processing of horizontal pulse output period T3, also enters the processing of horizontal pulse output period T4.If pulse is exported the phase
Between the drive pattern of T1, T2 renames as the 1st pattern, the drive pattern by pulse output period T3, T4 renames as the 2nd pattern, then
The driving being carried out by the 2nd pattern is accompanied with the driving being carried out by the 1st pattern, the driving being carried out by the 1st pattern with pass through
The driving that 2nd pattern is carried out is accompanied.In addition, in the driving being carried out by the 1st pattern, whole switch elements of being driven
Connecting number of times equal, in the driving being carried out by the 2nd pattern, the connection number of times of the whole switch elements being driven is equal.
Exporting period T1, T3 in pulse, the 11st, switch brachium pontis 14 is driven.Specifically, period T1 is exported in pulse,
Make switch brachium pontis the 11st, 14 whole switch elements i.e. switch element the 31st, the 32nd, the 37th, 38 carry out break-make simultaneously.Here, switch is made
Element 31 and switch element 37 carry out break-make simultaneously, make switch element 32 and switch element 38 carry out break-make simultaneously, so replace
Ground repeatedly, but is not limited to this.Pulse export period T3, from switch brachium pontis the 11st, 14 export when, drive switch bridge
Arm the 11st, 14 when, will switch brachium pontis the 11st, 14 respective switch elements in be more than or equal to 1 connection, and above or equal to
1 switch element disconnects.That is, exporting period T3 in pulse, the switch element being also turned in each switch brachium pontis is more than
Or be equal to 1, and less than the sum of the switch element in switch brachium pontis.
Exporting period T2, T4 in pulse, the 12nd, switch brachium pontis 13 is driven.Specifically, period T2 is exported in pulse,
Make switch brachium pontis the 12nd, 13 whole switch elements i.e. switch element the 33rd, the 34th, the 35th, 36 carry out break-make simultaneously.Here, switch is made
Element 33 and switch element 35 carry out break-make simultaneously, make switch element 34 and switch element 36 carry out break-make simultaneously, so replace
Ground repeatedly, but is not limited to this.Pulse export period T4, from switch brachium pontis the 12nd, 13 export when, drive switch bridge
Arm the 12nd, 13 when, will switch brachium pontis the 12nd, 13 respective switch elements in be more than or equal to 1 connection, and above or equal to
1 switch element disconnects.That is, exporting period T4 in pulse, the switch element being also turned in each switch brachium pontis is more than
Or be equal to 1, and less than the sum of the switch element in switch brachium pontis.
Additionally, the break-make number of times of the break-make number of times of pulse output period T1 and pulse output period T2 is equal, defeated in pulse
Going out period T1, T2, the pulse width during connection and the pulse width during disconnection are also equal.
In addition, the break-make number of times of the break-make number of times of pulse output period T3 and pulse output period T4 is equal, defeated in pulse
Going out period T3, T4, the pulse width during the connection of the switch element of energising is also constant.Further, each pulse export period T3,
T4, the break-make number of times of each switch element is equal.
In addition, export period T3, T4 by making the current ratio pulse during switching elements ON of pulse output period T1, T2
Switching elements ON when electric current little, thus pulse output period T1, T2 suppression switch element heating.Specifically,
As it is shown on figure 3, in the whole period from T1 to T4, make output electric current I during outputoutPeak value equal, make to output when defeated
Go out electric current IoutCarry out the time integral value after time integral also equal.Additionally, in figure 3, pulse output period T1, T2 open
Electric current when closing element switches is 1/2 of the electric current during switching elements ON of pulse output period T3, T4.Its reason is,
If being conceived to switch brachium pontis 11 as an example, then due to output electric current IoutPeak value equal in whole period, pass through
Make switch element 31 and switch element 32 be also turned at pulse output period T1, thus share output electric current, on the other hand,
Pulse output period T3 switch element 31 and switch element 32 are alternatively switched on, and do not share output electric current, therefore defeated in pulse
Go out period T1 flow through switch element the 31st, 32 electric current become pulse output period T3 flow through switch element the 31st, 32 electric current
1/2。
In such manner, it is possible to the heating of each switch element of suppressor pulse output period T1, T2, but signal is exported extremely
The heating of each driver of each switch element is big.Further, period T3, T4 are exported in pulse, although the heating of each switch element becomes
Greatly, but the heating of each driver by signal output to each switch element is suppressed.
In addition, pulse output period T1 and pulse output period T2 is set to a pair, by pulse output period T3 and pulse
Output period T4 is set to a pair.That is, after extra pulse output period T1, period T2 is being exported through extra pulse, through extra pulse output
Period T4 is exported through extra pulse after period T3.
By being driven in the above described manner, thus export period T1, T2 in pulse, due to the output electricity of supply unit 1
Stream is by the whole switch element output being connected in parallel in the switch brachium pontis being currently driven, therefore, it is possible to suppress each
The heating of switch element.Export period T3, T4 in pulse, due to being connected in parallel in the switch brachium pontis that is only currently driven
The output electric current of a part of output power supply device 1 of switch element, therefore, it is possible to the heating of suppression driver.
In addition it is also possible to according to processing conditions, the cooling capacity of supply unit, switch element pressure or driver
Pressure and pulse output period T1, T2, T3, T4 respective period is repeated identical number of times and is driven.I.e., it is also possible to
Carry out 2 T2 after carrying out 2 T1, after carrying out 2 T3, then carry out 2 T4.
By carrying out break-make control in the above described manner such that it is able to make the output electric current I of T1, T2, T3, T4 each periodoutPhase
Deng heating can be suppressed, and makes heating uniform.
