Verification of Digital Control of PWM Inverter using 50 MHz Sampling ADC with a Universal Smart Power Module (USPM) Controller

In the development process of power electronics system, a wide range of know-how is required for special purpose circuits such as main circuits, control circuits and gate drive circuits. The Universal Smart Power Module (USPM) has been proposed to solve these problems by converting the above circuits into one module to reduce the design cost and development time. Since the USPM is a combination of several circuits that modularize various functions, its controller requires the ability to perform high-speed digital calculation and high-speed sampling. In this paper, verifications were carried out for a single-phase PWM inverter using a 50MHz sampling ADC with the USPM controller. The performance of USPM controller was discussed.
