Output end.
The cardinal principle of the circuit is：
If positive bus-bar is higher with respect to negative busbar, it is assumed that the potential of+400V buses is 420V, the potential of -400V buses for -
400V.When Q100 conductings are switched ,+400V buses form loop by switching Q100, inductance L2, electric capacity C2, diode D3, give
Electric capacity C2 charges, and the voltage of electric capacity C2 is 420V after charging complete；Then switch Q101 conductings, the electric energy on electric capacity C2 is by electricity
Sense L2, switch Q101, diode D4 are released on -400V buses, now because 420V is more than 400V, the positive local derviations of diode D4
It is logical, the transfer of energy is completed, two balances of bus are maintained, the precision for flowing is improve indirectly, other Working state analysis
It is similar.
