Abstract Firstly, this paper analyzes the different resonant forms of the UHV frequency tuned resonant test power supply (UHV-FTRTPS) by the requirement of different testing. Then this paper presents three novel topological structures of UHV-FTRTPS, which combine the present power electronic technology: ①Based on the analog devices. ②Based on the PWM rectifier and H bridge inverter. ③Based on the uncontrol rectifier and H bridge inverter. This paper also discusses all structures working principle, and then deeply study on the power amplification circuit, over-current circuit and breakdown circuit of topological structure one. In addition, for the topological structure two, the source voltage estimation is presented in the PWM rectifier controller. Meanwhile based on the mathematical model of the inverter and resonant circuit, this paper presents the double closed loop control strategy, which takes resonant capacitor voltage as outer loop and output filter capacitor current as inner loop. The controlled variable of inner loop is a sine quantity, so the multi-mode recursive PID is used for it. Simulation and test results show that the proposed topological structures are feasible and the control strategies are valid.

Key words： UHVAC-testing supply voltage identification multi-mode recursive PID topological structure
