Abstract: An inverter system is provided. The inverter system has a first voltage zone and a second voltage zone isolated with each other. The inverter system includes a power unit, a controller, a power regulator, an isolated power supply, a driver and an inverter. The power unit in the first voltage zone provides an initial power. The controller in the first voltage zone generates a power control signal. The power regulator in the first voltage zone receives the power control signal and the initial power and outputs a first adjustable power accordingly. The isolated power supply has a primary part and a secondary part in the first and second voltage zones respectively. The primary part receives the first adjustable power, and the secondary part outputs a second adjustable power. The driver in the second voltage zone receives the second adjustable power and outputs an adjustable driving signal to control the inverter.

Abstract: A power module includes first and second electrode terminals adapted to electrically connect to a power source, a first switch element, a second switch element, a first Kelvin source pin, and a second Kelvin source pin. The first switch element is electrically connected to the first electrode terminal The second switch element is electrically connected between the first switch element and the second electrode terminal and includes a drain and a source electrically connected to the first switch element and the second electrode terminal respectively. The first Kelvin source pin is electrically connected to the source of the second switch element and is adapted to receive a gate drive signal for driving the second switch element. The second Kelvin source pin is electrically connected to the source of the second switch element and is configured to be electrically connected to a snubber circuit.
