That is to say, in energy recovery apparatus shown in Figure 3, adopted igbt to replace keeping high-end and keep the power switch pipe of low side in traditional energy recovery apparatus.Simultaneously, the energy in the traditional energy recovery apparatus recovers the power switch pipe that electric capacity and energy recover high-end and low side and does not use in according to the energy recovery apparatus of the embodiment of the invention.That is to say, energy recovery apparatus according to the embodiment of the invention has lacked on the usage quantity of power switch pipe much than traditional energy recovery apparatus, simultaneously, since igbt to open resistance little, saturation pressure reduces, so improved the efficient of system greatly, reduced power consumption, provide cost savings.
Fig. 4 is the control timing and the output waveform figure thereof of respective switch shown in Figure 3.A cycle period keeping the phase is divided into four-stage: supposition is at initial time, igbt M2 and M3 and power switch tube S 2 conductings, igbt M1 and M4 and power switch tube S 1 are ended, and the voltage Vxy maintenance-Vs on the screen capacitor C p is constant.
At first stage (t0-t1), igbt M2 and M3 end, the M1 conducting, power switch tube S 1 and S2 end, series resonance takes place by inductance L 2, diode D4 and igbt M1 in capacitor C p, and it is V that voltage Vxy on the screen capacitor C p and electric current I xy close over time Xy(t)=-V sCos (ω (t-t 0)), i xy ( t ) = V s L / C p sin ( ω ( t - t 0 ) ) 。Wherein, ω = 1 / LC p Be resonance frequency. i L ( t ) = i xy ( t ) = V s L / C p sin ( ω ( t - t 0 ) ) 。This process has been avoided the screen electric capacity impulse electricity process of suddenling change in the traditional circuit.
