摘要： PURPOSE: To suppress undesired high frequency voltage by connecting an AC power supply with a power storage means and operating a switch which takes out power only during the interval other than the connecting time interval. CONSTITUTION: A control circuit 13 at a power supply section 7 turns a transistor (Tr) 10 on in switching mode. A low resistance measuring resistor 31 is arranged in the connection line between a bridge rectifier 5 and a joint A and voltage drop due to a charging current is detected by means of a measuring amplifier 32. The measuring amplifier 32 generates, at the output end 33 thereof, a digital suppression signal which has a logical value of 0 when the charging current flows and a logical value of 1 during other time intervals. Consequently, an AND circuit 34 arranged in the line to the Tr 10 is turned off for a momentary interval. A disturbance is prevented from reaching an AC power supply 1 by interrupting the driving of the Tr 10 during a time when the bridge rectifier 5 is conducting thereby preventing occurrence of a disturbance.

摘要： PURPOSE: To provide the load power feeding circuit arrangement of simple constitution with less power loss by supplying energy from an AC power supply through a switch mode power feeding unit to at least one of two partial loads and directly supplying it to the other as desired. CONSTITUTION: Respective switches 5 and 6 are provided with the serial connection circuits of diodes 7 and 8 and FETs 9 and 10 and energizing is performed from the respective partial loads 3 and 4 to a connection point 11 between first and second load branching lines 3 and 5 and 4 and 6. Further, two divergence branching lines 12 and 13 and feedback branching lines 14 and 15 are respectively mutually serially connected between terminals 1 and 2. The respective divergence branching lines 12 and 13 are provided with the diodes, a current by the unidirectional conductive elements is small power loss and an additional control means is not required. Then, energizing is performed from a contact point 16 to one of the terminals 1 and 2 as desired without causing short circuit between them. Also, the feedback branching lines 14 and 15 are constituted of FETs, energizing is performed at optional time only in a direction from the connection 17 to the terminals 1 and 2 and a unidirectional semiconductor switch is used similarly to the switches 5 and 6. Thus, the lowest power loss is designed with a manufacture cost.

摘要： PURPOSE: To regulate the supply of power finely by supplying an energy to a load by the power supply unit with a switch mode within a power consumption range, that is equal to or less than a limited power. CONSTITUTION: The DC side of a rectifying bridge 1 is connected, after a load 6 and a switch 7 are connected via terminals 4 and 5. A power supply unit 9 with a switch mode is inserted between the terminals 4 and 5 and a connection point 8 of the load 6 and the switch 7. When a semiconductor switch 12 is driven in conduction state, a current flows from the terminal 4 of the rectification bridge 1 to the terminal 5 of the rectifying bridge 1 via the load 6 and a capacitor 10. Then, when the semiconductor switch 12 is set to cutoff state, a coil current that is accumulated in a coil 11 flows to the load 6 and the capacitor 10, via a free wheel diode 14. To supply a maximum power to the load 6, the switch mode power supply unit 9 is deactivated, and the switch 7 is activated instead.

摘要： PURPOSE: To supply a load with energy uniformly by starting the conduction phase of each switching element at a moment when the voltage at an associated terminal of a main power supply drops below the voltage of at least one other terminal and extending the conduction phase over a part of period of an AC voltage corresponding to the number of the terminals. CONSTITUTION: The power supply circuit arrangement for load comprises a voltage source 1 for supplying a main AC voltage UV, and main impedance 2, 3 arranged symmetrically to two earths. Energy storage units 11, 12 are connected, respectively, with the DC branch terminals of a bridge rectifier comprising associated rectifier stages 7, 8 and 9, 10. The energy storage units 11, 12 are connected through switching elements 13, 14 with a load 15 which is fed with energy from the energy storage units 11, 12 upon conduction of an associated switching element 13, 14. The energy flow is interrupted when the switching elements 13, 14 are in blocking state The switching elements 13 14 are activated by a control circuit (not shown) through control terminals 16, 17.
