Systems and methods for power switch control for inverter for electric vehicle

A system comprising:

• a power switch driver configured to:
• receive a pulse to control an operation of a power switch,
• generate, based on the received pulse, a first signal to the power switch to increase a gate voltage level of the power switch at a first rate from an off-state gate voltage level to a first on-state gate voltage level in a first time period, and
• generate, based on the received pulse, a second signal to the power switch to increase the gate voltage level of the power switch at a second rate, less than the first rate, to a second on-state gate voltage level in a second time period subsequent to the first time period,
• wherein the power switch driver includes one or more of:
• one or more diodes to control flow of current from an external power supply, or
• one or more resistors to control the first rate and the second rate.

A system comprising:

• a gate driver configured to receive a pulse to control an operation of a power switch, and generate a gate signal based on the pulse;
• and
• a waveform controller configured to:
• receive the gate signal from the gate driver,
• generate, based on the received gate signal, a first signal to the power switch to increase a gate voltage level of the power switch at a first rate from an off-state gate voltage level to a first on-state gate voltage level in a first time period, and
• generate, based on the received gate signal, a second signal to the power switch to increase the gate voltage level of the power switch at a second rate, less than the first rate, to a second on-state gate voltage level in a second time period subsequent to the first time period,
• wherein the second rate is configured to cause the power switch to increase to the second on-state gate voltage level with reduced oscillations relative to oscillations of the gate voltage level of the power switch in the first time period.
