Abstract: 본 발명은 진폭을 펄스의 폭으로 변환하는 기능을 가진 PWM(Pulse Width Modulation) 제어부에 연결된 소프트 스타트 회로와 이를 포함하는 전원공급장치에 관한 것이다. 본 발명은 전원공급장치의 스타트 업시 소프트 스타트 회로를 이용하여 PWM 제어부에서 생성되는 상기 캐리어 신호의 주파수를 높여 한 주기의 길이를 짧게 하고, 스타트 업으로부터 일정 시간 후에 캐리어 신호의 주파수를 정상 주파수로 낮춘다. 이에 따라 본 발명은 캐리어 신호의 주파수에 동기되어 생성되는 PWM 제어부의 듀티 신호에 동기하여 전원공급장치가 동작하므로, 스타트 업시 전원공급장치가 정상 동작시보다 낮은 피크치의 전류로 동작할 수 있게 한다.

Abstract: A charge equalization apparatus is provided to improve charge equalization by inducing a magnetized current to a low charged battery and performing additional charge equalization. A charge equalization apparatus includes N charge equalization units(1001-100n), an inter-module equalization unit(110), and a voltage detection and driving signal generation unit(120). N charge equalization units are coupled to M batteries, and receive a charge from M batteries. N charge equalization units equalize the charge of M batteries which are coupled in series by discharging an over-charged battery and charging a low charged battery. The inter-module equalization unit is coupled to N battery modules in parallel, and equalizes the charge of N battery modules by discharging an over-charged battery module of N battery modules and charging a low charged battery module. The voltage detection and driving signal generation unit detects a voltage of each of M x N batteries, and sets an average voltage of the detected voltage as a reference voltage. The voltage detection and driving signal generation unit generates a driving signal based on the detected voltage value and the reference voltage. The voltage detection and driving signal generation unit controls the driving of N charge equalization units and the inter-module equalization unit by providing the generated driving signal to N charge equalization units and the inter-module equalization unit.

Abstract: An asymmetric control DC-DC converter using a NAND gate is provided to implement an asymmetric gate signal simply by controlling the asymmetric control circuit with a simple NAND gate instead of an exclusive chip. An asymmetric control DC-DC converter using a NAND gate includes a converter unit(20) and an output voltage control unit(30). The converter unit converts a first voltage of a first level into a second voltage of a second level by a switching operation of a switching unit. The output voltage control unit maintains a constant level of the second voltage. The output voltage control unit includes an output voltage detection unit(31), and a PWM(Pulse-Width Modulation) control unit(32), and a gate signal generation unit(33). The output voltage detection unit detects an output voltage outputted from the converter unit. The PWM control unit receives the output voltage and generates a PWM control value. The gate signal generation unit receives the PWM control value and generates a switch driving signal of the switching unit. The gate signal generation unit includes first and second gates, which receive the PWM control value, and a third gate which receives an output of the second gate. The first, second and third gates are NAND gates.

Abstract: A charge equalization apparatus is provided to facilitate a manufacturing process of the charge equalization apparatus by winding secondary windings on plural transformers independently of each other. Transformers(T1-TN) include primary and secondary windings. The primary windings of the transformers are parallel-coupled with each other. The secondary windings are parallel-coupled with a battery. First current deliver elements(D1-DN) are series-coupled to the respective secondary windings. Battery cells(B1-BN) are parallel-coupled with secondary windings of the transformers. One end of the battery cell is connected to one end of the primary winding. A first switch(S) controls a current flow in first and second directions in the primary winding. A voltage sensing/switch driving signal generator(200) detects voltages of the battery cells and turns on/off the first switch. When the first switch is turned on, current flows in the first direction in the primary winding and an induction current is generated in the secondary winding, so that charges are equalized in the battery cells.
