摘要（英）：

The phase synchronization control module of the chip is connected to pseudo-random multifrequency signal synthesis (PRMSS) module. PRMSS module is connected to IGBT-H type inversion bridge dead zone control (IBDZC) module. IGBT-H type IBDZC module is connected to timing source module, and over current and alarm signal process (OCASP) module respectively. OCASP module is connected to IGBT-H type inversion bridge. The frequency divider for high frequency signal is connected to the phase synchronization control module. After electrical connection, program is programmed in the programmable logic circuit chip. When control signal is provided, the invention can generate multifrequency pseudo-random signal source. Features are: produced signal in high precision, few time delay, and provided function for protecting dead zone of IGBT module.
