Background technology
The treadmill of home sale is the 220V mains-supplied at present.But the existing 220V power supply power supply of the treadmill of overseas market demand, also there is the 110V power supply to power.Along with the continuous developing of overseas market,, must design the treadmill circuit of 110V power supply power supply for satisfying some external client's demand.
But, if develop the treadmill circuit of 110V power supply power supply separately, not only the construction cycle long, and can cause the minimizing of general part kind, buying and the increase of stock's kind and problems such as buying, storehouse management, production and maintenance cost rising.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of booster circuit of treadmill is provided.This booster circuit is added on the former 220V power supply power supply treadmill circuit, can realizes the 110V power supply.Can satisfy the demand of external client to the treadmill of 110V power supply.Circuit is simple, and general part is wide in variety, has avoided the too much increase of buying and stock's kind and the bigger raising of buying, storehouse management, production and maintenance cost.Can be applicable in the treadmill of 110V power supply.
In order to achieve the above object, the utility model is connected with interchange 110V attaching plug.An end A who exchanges the 110V attaching plug connects the input of rectifier circuit, and the direct current of output is given former 220V power supply power supply treadmill circuit supply between the output of rectifier circuit and the ground end thereof.The other end B that exchanges the 110V attaching plug divides two-way.One the tunnel connects the positive pole of first group of 3 electrochemical capacitor in parallel, the minus earth end of these first group of 3 electrochemical capacitor in parallel through a current-limiting resistance; Another road connects the negative pole of second group of 3 electrochemical capacitor in parallel and the positive pole of first group of 3 electrochemical capacitor in parallel.Promptly export 220V between the positive pole of second group of 3 electrochemical capacitor in parallel and the ground and give former 220V power supply power supply treadmill circuit supply.
The capacity of each in first group and the second group electrochemical capacitor in parallel all is 680 μ F, withstand voltage 200V.Current-limiting resistance can prevent that charging current is excessive, the protection electrochemical capacitor.
After connecting the 110V AC power, first group and second group of electrochemical capacitor in parallel are recharged, and the cathode voltage of second group of 3 electrochemical capacitor in parallel will soon be raised to about 220V.The parameter effect of 6 electrochemical capacitor 680 μ F, withstand voltage 200V is better.The electrochemical capacitor of each 680 μ F can be realized the current capacity of 2.5A under two times of situations of boosting.The change of the parameter by rectifier circuit and electrochemical capacitor can also change the power of integrated circuit.
The control contact of a relay in parallel respectively between the negative pole of the two ends of current-limiting resistance and B end and second group of 3 electrochemical capacitor in parallel.In parallel with an afterflow backward dioded again behind the coils from parallel connection of coils of two relays, its two ends C and D are connected on the plug.This plug is pegged graft with the main control circuit of treadmill again.
When power increases to 1000W when above, the charge and discharge process that relay can timesharing control electrochemical capacitor, the excessive impact of electric current when reducing electrochemical capacitor and discharging and recharging to electric supply installation.The afterflow backward dioded is used to protect the main control circuit of treadmill.
Task of the present utility model comes to this and finishes.
The utility model is added on the former 220V power supply power supply treadmill circuit, can realize the 110V power supply.Can satisfy the demand of external client to the treadmill of 110V power supply.Circuit is simple, and general part is wide in variety, has avoided the too much increase of buying and stock's kind and the bigger raising of buying, storehouse management, production and maintenance cost.Can be applicable in the treadmill of 110V power supply.
