Description

The high-voltage inverted power frequency pulse power

The utility model relates to power supply, more particularly relates to the power frequency high voltage inversion pulse power.

The existing power frequency high voltage pulse power all is to utilize transformer to boost, and with electric capacity sinusoidal wave top is flattened simultaneously.The shortcoming of this method is that efficient is low.

The purpose of this utility model provides a kind of pulse flat-top longer duration, and duty ratio is big, the high-voltage inverted power frequency pulse power that efficient is high

The purpose of this utility model is achieved in that a kind of high-voltage inverted power frequency pulse power, it is characterized in that it comprises: rectification circuit, the output of rectification circuit is carried out the capacitor filter of filtering, the direct voltage that obtains through filtering is become the inverter bridge circuit of pulse voltage, and step-up transformer that the pulse voltage of inverter bridge circuit output is boosted and the lock-out pulse that produces the control impuls of inverter bridge circuit take place and control circuit.

Said inverter bridge circuit is deleted bipolar transistor by insulation and is constituted.

Good effect of the present utility model:

1, because the utility model is to delete bipolar transistor IGBT with insulation to carry out inversion, so pulse flat-top longer duration, duty ratio is big, the efficient height;

2, circuit is simple and output frequency is identical with incoming frequency, can be suitable for two kinds of power supply standards of 50HZ or 60HZ.

Fig. 1 is a block diagram of the present utility model.

Fig. 2 is a schematic diagram of the present utility model.

Below in conjunction with accompanying drawing the utility model is described in further details.

The utility model is made up of 5 parts: is the 220V50HZ rectification 310V direct voltage rectification circuit 1, and pulsating voltage is carried out the capacitor filter 2 of smothing filtering, is the inversion of 310V direct voltage that the insulation of pulse voltage is deleted bipolar transistor (IGBT) inverter bridge circuit 3, the pulse voltage of IGBT inverter bridge circuit output is boosted to 6.5KV step-up transformer 4, produces pulse generation and control circuit 5 to the control impuls of IGBT.

Fig. 2 is a schematic diagram of the present utility model, in fact is an embodiment.ZLQ is to 220V50HZ (60HZ) ac voltage rectifier of input, C1, C2 carry out smothing filtering to pulsating voltage, two winding L 1 of B1 level of transformer, the identical voltage of L2 output, behind Z1, Z2 slicing, control voltage as IGBT, the conducting in turn of control T1, T2 makes filtered voltage inversion be and the pulse voltage of power supply same frequency, and raising through B2 is the voltage of 6.5KV again.
