Title: Resonance type switching power supply
Inventor: YUKI HITOSHI
IPC: H02M3/28
Filed: 1988-01-28
Abstract: PURPOSE:To stabilize the output voltage inexpensively and easily, by controlling the magnitude of the driving current of a switching transistor in accordance with the magnitude of the output voltage on the secondary side of a power transformer. CONSTITUTION:The DC input voltage Vin of a resonance type switching power supply is obtained from a commercial AC power source 1 through a rectifying circuit 2 and a smoothing capacitor 3, which is then turned ON and OFF by a transistor(Tr) Q1 of a switching element through the primary winding Na of a transformer T1. Output voltage Vout is supplied from the secondary winding N2 of a power transformer T2 through a diode D4, etc. The output voltage Vout is fed back to the Tr Q1 through a photocoupler 8. Since the driving current is reduced when the output voltage Vout increases, the output voltage is so controlled that the ON-period of the Tr Q1 is shortened. Consequently, the stabilization of the output voltage can be effected.

Abstract: PURPOSE:To make it possible to adjust the flow quantity of vaporized fuel by a high pressure, and to re-inject fuel by a market-sold gas lighter cylinder to greatly improve the usability by hermetically closing the set area of the opening surface of a porous substance, and after the tight closure, adjusting the flow quantity of evaporated fuel by a clearance between a flow quantity adjusting cylinder and a valve device. CONSTITUTION:The valve device 13 operates in linkage with a control lever 28, and acts responsive to the movement of a thermal responding element 41. At the time of starting, the valve device 13 reaches a predetermined temperature rapidly. Therefore, the flow quantity of the evaporated fuel is made large, and the thermal responding element extends as the temperature increases. Thus, a control valve 15 mounted on the valve device 13 hermetically closes only the set area of the opening surface of the porous substance 11, and reduces the flow quantity of evaporated fuel whereby the heat generation quantity of the catalyst 28 is reduced and the temperature rise of the heat transmitting member 39 is made slow. Further, when the temperature of the heat transmitting member 39 exceeds the set temperature, the thermal responding element 41 further extends, and the clearance between the valve device 23 and the flow quantity adjusting cylinder 12 is narrowed, whereby the flow quantity of the vaporized fuel is reduced and also the heat generation quantity of the catalyst 28 is reduced, and the temperature of the heat transmitting member 39 is adjusted to the set temperature.

Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To obtain the controller which can have stable control performance even if known disturbance varies and maintain high-precision control performance by a learning function even if characteristics of a process vary with the time by using a learning type dynamic compensator. SOLUTION: A closed-loop system has a controller 2 which outputs a manipulated variable for a specific process according to a command value (r). A subtracter 3 finds control deviation by subtracting the controlled variable (y) of the process 1 from a command value r* obtained by correcting the command value (r). A feedforward signal generator 5a inputs at least one of known disturbance (d) and command value (r) and outputs a feedforward signal. An adder 4 adds this output and the output from the controller 2 together and outputs the manipulated variable (u) of the process 1. A parameter learning unit 7 calculates a necessary parameter A by a learning function on the basis of a manipulated variable (u) and the known disturbance (d), and the controlled variable (y) and corrected command value r* and outputs it to a feedforward signal generator 5a.
