Technical field
The utility model belongs to technical field of electricity, relates to the device of a kind of capacitor fast charging accumulation of energy and heavy-current discharge, specifically is that a kind of portable engine starts power supply.
Background technique
During engine start, need supporting startup power supply, existing market has two types product: 1, power frequency transformer is joined rectifier, what power was bigger can export the above inrush current of 2000A, but the volume of power supply is near 0.5～0.8 cubic metre, and weight is that Kg more than 300 (in order to improve output current, must reduce the internal resistance that starts power supply as far as possible, so can only design the power transformer that adopts larger capacity, the internal resistance that 2000A/24V starts power supply is designed to 2 milliohms); 2, high frequency switch power, volume and weight are little much than power frequency transformer, but output current is less, is below the 500A mostly, realizes that the output current of 1000A is very difficult.
Existing engine start power supply, otherwise be exactly that volume is big and heavy, cost height and be inconvenient to carry, otherwise be exactly that the output current performance is difficult to reach usage requirement.
The model utility content
The utility model is bigger at engine start power volume and weight in the prior art, is not easy to carry, and provides a kind of portable engine to start power supply.
The utility model can be solved by the following technical programs:
A kind of portable engine starts power supply, it is characterized in that comprising dc output power pincers, capacitance group and constant current/constant voltage HF switch charger; The positive and negative electrode of the dc output end of described constant current/constant voltage HF switch charger connects the positive and negative electrode of capacitance group respectively, and the positive and negative electrode of capacitance group connects the dc output power pincers respectively.
Further, described dc output power pincers are general power supply pincers.
