Summary:The utility model discloses a programmable pseudo random multifrequency signal chip. Thereof phase synchronous control module is connected to a pseudo random multifrequency signal synthesis module which is connected to an IGBT-H type inverter bridge dead zone control module, and the IGBT-H type inverter bridge dead zone control module is separately connected to a clock source module and an over-current and alarming signals pressing module, and the clock source module is connected to the over-current and alarming signals pressing module which is connected to the IGBT-H type inverter bridge, and a high-frequency signal frequency divider module is connected to the phase synchronous control module. The utility model is programmed into a programmable logical chip after electrical connection. The utility model can generate a multifrequency pseudo random signal source only if a control signal is provided; and the utility model has the advantages of high precision of signal generation and shorter delay, which also pr
