Abstract: An abnormal voltage protection circuit of an inverter is provided to protect the inverter safely when an input voltage is in both low and overvoltage states. An abnormal voltage protection circuit includes a zener diode(ZD2), a low voltage comparator(U1), and an overvoltage comparator(U2). The zener diode is connected to an input voltage(Vin), and a switching voltage thereof is set at a reference level of a low voltage. The low voltage comparator has a positive terminal connected between the zener diode and the input voltage and a negative terminal connected to standby voltage(STBY) in a constant voltage state. An output of the low voltage comparator is connected to a low voltage switching terminal of the inverter. The low voltage comparator turns off the inverter by outputting a logic low to the low voltage switching terminal of the inverter when the input voltage is in a low voltage state. The overvoltage comparator has a negative terminal connected to the output of the low voltage comparator and a positive terminal connected to the standby voltage. An output of the overvoltage comparator is connected to an overvoltage switching terminal of the inverter. The overvoltage comparator turns off the inverter by outputting the logic 'low' to an overvoltage switching terminal of the inverter when the input voltage is in an overvoltage state.

Title: Radio frame scheduling method in mobile communication network
Inventor: HAN SEUNG HEE
IPC: H04B7/26
Filed: 2007-05-15
Abstract: A method for scheduling a radio frame in a mobile communication network is provided to perform efficient channel estimation and data transmission by applying different data transmission schemes to a time domain multiple PSC(Primary Synchronization Code) section among the radio frame of an MBMC(Multimedia Broadcast Multicast Service), and the remaining MBMS section. A method for scheduling a radio frame in a mobile communication network includes the following several steps. The first PSC(PSC_t0) is transmitted with zero of a subframe timing offset with respect to global time, the second PSC(PSC_t1) is done with one of the subframe timing offset and the third PSC(PSC_t2) is done with two of the subframe timing offset. Accordingly a P-SCH, an S-SCH, a P-BCH and an RS which are used in detecting cells are time-shifted with an offset in accordance with each PSC. In a section A overlapped with time-shifting, normal SFN(Single Frequency Network) combining can not be performed, so a data transmission mode where an MBMS transmission mode is excluded is applied to the section A and a typical MBMS transmission mode is applied to a section B which is a remaining section except the section A by using TDM(Time Division Multiplexing). In order to do this, a base station performs scheduling such that a unitcast mode is applied to the section A and a multicast mode or a broadcast mode is applied to the section B by using the TDM. In case of a system not providing the MBMS, the unicast mode can applied to both the section A and the section B.
